CAESAR II 2016 Hot Fix 4 Revisions and Changes, Version 08.00.00.5604

General

  • Fixed an issue regarding import data on the EJMA Expansion Joint Rating dialog box. Previously, when you clicked Get Data From Input File on the Geometry tab of the EJMA Expansion Joint Rating dialog box, the software populated data for all fields except Effective Diameter. The software now imports all the necessary data from the input file. (DM-TX-16597)
  • Fixed an issue in which report data did not display on the Restraint Summary report in the Static Output Processor. Previously, if you performed a Harmonic dynamic analysis, the Restraint Summary report did not contain any harmonics summary data. The issue is now resolved. (TR-TX-15609)
  • Fixed an issue in which the software truncated load type multipliers in the Static Analysis - Load Case Editor to integer values in some situations. For example, in the load case 0.1W + 0.2T1 + P1, the software converted the load case to 0.1W + 0T1 + P1. This caused the results to vary greatly from user expectations. The software no longer truncates or changes multiplier values in load cases. (TR-TX-16526)
  • Fixed an issue where the software displayed an incorrect prompt regarding running a version of CAESAR II that was released more than two years ago. This prompt displayed in CAESAR II 2016 (version 8.0), which is less than two years old. The prompt was removed. (TR-TX-16810)
  • Resolved a licensing issue when you launched NozzlePRO from the CAESAR II main menu. The software successfully opened, but later put the user into demo mode. If you have an Intergraph CAS NozzlePRO license and click NozzlePRO in the main menu, the software now opens the third-party software and you have full capabilities in the program. (TR-TX-16817)
  • Disabled the Search tab in the online help due to an issue that causes the software to unexpectedly quit. This issue will be researched and the Search tab re-enabled when the problem has been resolved.

CAESAR II 2014 SP2 Revisions and Changes

Piping Input and Materials

  • Fixed issues in the Piping Input where the software did not retain column width changes in the List Input dialog boxes. In addition, resolved issues with the Reset Default Properties option in the context menu. The software displayed a cutting plane on the model when you right-clicked and selected Reset Default Properties if you had not clicked in the grid prior to selecting the option. Also, the context menu did not stay open when you released the right mouse button. Now, the context menu functions as expected.
  • Resolved an issue with the Seismic Wizard in Piping Input, where the software did not revise the uniform loads vector values if the model is in Z-up orientation when you run the wizard. The software now recognizes the new orientation and shows the correct vector values in the Uniform Loads auxiliary panel.
  • Resolved an issue in Piping Input with line numbers when importing piping files into an existing piping job. When you selected Environment > Include Piping Input Files and chose a file to include, the software did not display the line numbers from the included file in the Line Numbers dialog box or on the model. CAESAR II now displays line numbers from any included job in Line Numbers dialog box and on the model.
  • Fixed an issue where, when you selected the entire Elements list input (by clicking in the left corner of the list input) and clicked Duplicate in the block commands, the software stopped responding.
  • Fixed a display issue with the Job Title dialog box in Piping Input. If you typed a full line (75 characters) in the title, when you reopened Job Title dialog box, the software inserted a blank line after the full line. The software now does not insert a blank line when you have a full line of text in the Job Title dialog box. 
  • Fixed an issue where the software stopped functioning when you attempted to renumber a large block of elements if an element from structural or piping file was included (imported) and the elements from that file were in the renumbering selection. In addition, the software did not prompt you if you tried to perform a block command (Rotate, Duplicate, Invert) when no elements were selected. The software now lets you renumber models that have included files in them. Also, the software alerts you if you try to perform a block operation without any elements selected.
  • Resolved an issue with material names in the CAESAR II Material Database Editor. Previously, the software had issues when you entered a material name of 16 characters. You can now only enter a material name of 15 characters or less in the CAESAR II Material Database Editor.

Piping Codes and Calculations

  • Fixed an issue with the Axial SIF (ia) value for jobs that use the B31.3 2012 code edition. When you entered a value of 1.0 for the Axial SIF (ia) for any non-bend elements in the piping input, the software used the Out-Plane SIF (io) value in the calculations, instead of the specified Axial SIF (ia) value. CAESAR II now recognizes any value entered in the Axial SIF (ia) and does not use the Out-Plane SIF (io) value unless you do not specify an Axial SIF (ia) value.
  • Updated the software and user documentation to support ASCE 2010 and IBC 2012 seismic load evaluation.
  • Fixed issues with ISO 14692 jobs where the software did not correctly calculate and display bend SIF information on the Stresses and the Miscellaneous Data output reports and the Bend SIF Scratchpad when you specified an EH/EA value in the piping input. In addition, the software was not displaying the EH/EA values or the Hand Lay check box selection made on the Allowable Stresses auxiliary dialog in the applicable Allowables list input columns.
  • Resolved issues with units conversions for jobs using the BS 7159 or UKOOA codes when you used a custom units file. The issues resulted in discrepancies in calculations between the Bend SIF Scratchpad in Piping Input and the results in the Static Output. The scratchpad calculations now show the same results as the Static Output. (TR-TX-12418)

Graphics/3D Model

  • Resolved an issue with resizing elements and the Lock Graphics function. If you selected Lock Graphics without resizing any anchor, restraint, or hanger, when you unlocked the 3D model, the software resized the elements to their largest size. Now, the software retains the element sizing when you unlock the graphics on the model.
  • Resolved several graphical interface issues when using the Lock Graphics option in the 3D Model. In addition, resolved inconsistent block operation behavior, fixed a From Node input response issue, corrected the units of measure in a few tooltips, and revised the default behavior for keeping or updating material warnings if you exit out of the prompt.
  • Fixed an issue with the Insert Element and Reset Plot options. When you opened a job with the List Input dialog boxes closed, and you clicked Insert Element, the software did not open the Insert Element dialog box. In the same scenario, if you changed the model and clicked Reset Plot, the software did not return the model back to its default state. These options now function as expected when the List Input dialog boxes are closed.
  • Resolved an issue with visibility options for Smart 3D and Smart Plant Review files when you loaded a VUE file. The issue stemmed from a missing .XML file.
  • Fixed a display issue with the visibility options for anchors, restraints, hangers, and structures on the 3D model in Piping Input, Isogen, and Static Output. When you selected the visibility options for these components, the software did not change the model visibility as expected. The Visibility options now function as expected.
  • Resolved a graphics issue in analyzed models when you selected Options > View Animation from the Static Output Processor or the CAESAR II Dynamic Output. The software closed when you selected an element on the model, changed the load case, and then double-clicked anywhere else in the model. This issue was resolved and the software functions as expected.
  • Fixed inconsistencies with the behavior of the Show/Hide check box on the Line Numbers dialog box in the piping input. The issues related to parent/child selections, included jobs selections, and unassigned line numbers on child selections. In addition, resolved inconsistencies with the Reset Visibility option. 

Analysis

  • Updated stress calculations for B31.3 jobs using Occasional (OCC) and Hydrotest (HYD) load case conditions. The CAESAR II development team revised stress calculations for the Sustained (SUS) condition after the B31.3 code committee moved Code Case 178 into the B31.3 code standard. The software now uses the same stress calculations for Occasional and Hydrotest conditions, which reflects the code standard.
  • Note: This change results in different code stress values for jobs that use the OCC and HYD load cases, especially jobs that have significant torsion stresses.

Hanger Design

  • Corrected an issue during hanger design where the specification of multiple Elastic Modulus values prevented optional boundary condition releases. This issue affected the loads produced in the restrained weight load case, which could subsequently affect the spring hangers selected. The software now allows boundary condition releases when there are multiple Elastic Modulus values specified.
  • Enhanced the Hanger Table and Hanger Table w/ Text output reports to show more characters for Node (the hanger node name). The character addition also displays when you send the reports to Microsoft Word or Excel. In addition, send a hanger report to Microsoft Word, the software displays the report in landscape mode.

Output Reports

  • Resolved an issue with the Send to Printer option in the Static Output Processor. When you generated a stress report on any analyzed job that used the Stoomwezen piping code and selected Send to Printer in the Output Viewer Wizard, the software did not print the Stoomwezen Approval Certificate. The software now prints the certificate when you select Send to Printer and generate the output report.
  • Resolved an issue with input echo reports in the Output Viewer Wizard of the Static Output Processor. When you sent reports to a text (ASCII) file, if there was an input echo report included, the software did not append the input echo information to the existing output. The software was over-writing previous reports listed before the input echo in the Output Viewer Wizard. The software now appends the output from reports and the input echo, instead of generating it as a new output report.
  • Fixed the display of the build number in certain Input Echo and Output text reports. The software was only displaying part of the build number in the header information in some reports.
  • Resolved an issue where, when you analyzed an individual structural model to use the Z-up vertical axis, the software did not display the Z-up change on any output reports that include direction (such as the Displacements, Global and Local Element Forces, and Restraint reports). The software now correctly displays the Z-up vertical axis on output reports that include direction.

Integration/Interoperability

  • Data Export (ODBC Database) – Resolved an issue with the Data Export Wizard (ODBC Database) with Microsoft Access 2010 (.accdb) format. The software now successfully exports to an .accdb file.
  • PCF Import – Made several improvements to CAESAR II PCF Import to resolve issues related to pressure and temperature piping input values. Resolved an issue of missing component attributes when importing in a Smart 3D PCF into CAESAR II. Also, updated the software to ignore a status attribute related to drawing when importing PCFs from CAD.

Stress Isometrics

  • Fixed an issue with annotations for material names in the Isogen module where the software did not display the material name in the drawing when you generated stress isometrics. The software now displays the material name annotations on the generated drawing.
  • Resolved an issue with annotations on bends when generating stress isometrics. When you added annotations on a center-point of a 90-degree bend and created an isometric drawing, the software displayed two 45-degree bends on the drawing. This issue was resolved for the bend center-point annotations, and the software now shows one 90-degree bend on the drawing.

Error Checks

  • Fixed an issue with the Nozzle Limits Check where the Error Checker improperly reported an error on a 45-degree nozzle.
  • Resolved an issue during error checking with WRC 297 nozzle identification. The issue, when manifested, caused the software to generate misleading error messages, which also prevented the analysis of the model.
  • Fixed the display of node numbers in certain types of errors reported in the Error Checker. When you analyzed a piping input job and ran the Error Checker, if an error occurred involving a coordinate mismatch of elements, the software displayed different node numbers in the Element/Node Number column than in the Message Text. The software now displays the same node numbers shown in the Message Text and the Element/Node Number column.

User Documentation

  • CAESAR II 2014 documentation is now available in Japanese. When you select Language > Japanese on the interface, the software displays the online help and guides in Japanese.


CAESAR II 2014 SP1 Revisions and Changes

Configuration

  • Corrected the default value for the SIFs and Stresses>SIF Multiplier for the Sustained Stress Index configuration setting during initial installation. There is now a warning for users who may have already used the setting with its defaults, alerting them that using a SIF multiplier value of 1.0 can cause results that differ from the recommendations by B31.3.

Piping Input, Calculations, and Materials

  • Revised the functionality of the Allowable Stresses auxiliary panel when you select B31.3 as the code, with regard to software defaults for the <f> Allowed Maximum of 1.2 radio button (cyclic reduction factor).
  • Corrected the coefficient of thermal expansion for some duplex and super-duplex steels (A789/A790) in the Material Database based on ASME B31.1 (Table B-1 Thermal Expansion Data, Group 2 – Low Alloy steels) and TEMA 8th Edition (Table D-1) standards.
  • Fixed issues with data consistency in the Material Database Editor when there are anomalies with data entry (such as incorrect data ordering or blank fields).
  • Enhanced the Optimization (Loop) Wizard to improve the stability and robustness of the wizard by handling a wider range of target values. The wizard now automatically chooses the most economical solution based on your target input, which often reduces the number of iterations required for a solution.
  • Fixed an issue when you clicked Analyze multiple times and the software exited you out of the piping input. Multiple clicks on Analyze now act as a single click without issue.

Analysis

  • Updated several internal calculations for the ASCE 7 2005 wind code to comply with the standard. Changes related to the wind direction factor, minimum wind force, and the topographic factor (Kzt).
  • Resolved an issue with B31.8 minimum wall calculations in the Error Checker when you did not specify a design factor (Fac) in the Allowable Stresses auxiliary panel for piping input. The software now uses a default value of 0.40 if you do not specify a Fac value, which follows code standards.
  • Resolved some issues with B31.8 SIF calculations for extruded outlets, reinforced fabricated tees, and for the Butt Weld SIF/Tee type.
  • Fixed an issue with stress calculations for intersections in ASME NC/ND and RCC-M C/D jobs. The software now uses the effective section modulus for intersection stress calculations for ASME NC/ND and RCC-M C/D jobs.
  • Changed the longitudinal and hoop stress calculations for PD 8010-1. The software now applies either a thin- or thick-walled equation for the calculations based on the D/t ratio, as specified by the piping code.
  • Fixed an issue with local restraints that caused the software to display an Insufficient Memory prompt and to not complete the static analysis when you were using a very large number of local restraints (thousands) in your model.
  • Resolved an issue with wave loading with regard to hydrodynamic coefficients (Cd, Cm, and Cl). The software now correctly calculates hydrodynamic coefficients in wave loads at 90- and 270-degree angles.
  • Resolved an issue in the Dynamic Analysis module where the software could not complete calculations for Fatigue (FAT) stress types and Fatigue Cycles in Spectrum Load Cases.

 

Long File Paths/File Names

  • Completed background research to identify all areas of the software where there were issues with long file names and long file paths. Research identified the following areas with issues:
    • Fixed an issue with file paths in the Classic Piping Input when you included a piping or a structural file that had a long file path into an existing job and saved the job.
    • Resolved an issue with file paths in the Classic Piping Input for structural jobs when there was an include file attached for pipes or structures and a problem with long paths on include files (piping or structural).
    • Fixed an issue with file paths and file names in the C2Isogen module (Output > Generate Stress Isometrics). 
    • Resolved an issue with file paths in the Buried Pipe Modeler.

Integration

Data Export (ODBC Database)

  • Improved how CAESAR II lists details for constant effort support in exported hanger ODBC Database reports.
  • Corrected the figure number (hanger type) in the hanger reporting in the Data Export Wizard (ODBC Database) and Static Output Processor for LISEGA spring cans. 

CAESAR II Neutral File

  • Fixed an issue with memory management for a few of the CAESAR II example jobs when using the CAESAR II Neutral File Interface. The example jobs now convert successfully to a neutral file without any issues.

CADWorx Interface

  • Fixed an issue with materials when using the CADWorx C2OUT function to CAESAR II. The software now retains the CADWorx material assignments when you run the C2OUT function in CADWorx and then review them in CAESAR II. 

Miscellaneous

  • Enhanced the software to make internal CAESAR II version information available to third-party software through an internal translation DLL, which makes the version information available for input files (._A and .c2 files). 
  • Added a new internal file extension type, MiM, which the software uses in the job archive for interaction with PRG products. 

Output Reports

  • Resolved an issue with the Stoomwezen Approval Certificate where the complete job pathname and approval date did not display when you generate the certificate on an external application.
  • Resolved several issues with the Stress Summary report. 
  • Stress Isometrics
    • Renamed the output PCFs the software creates when generating isometric drawings to distinguish them from input PCFs. Now, the software appends “SISO” to the file name and to all subsequent isometric files generated from CAESAR II. 
    • Fixed a symbols display issue on generated ISOGEN drawings when in Isometric view. CAESAR II now displays unique symbols to distinguish between spring hangers and spring cans on the ISOGEN drawing.
  •  WRC 107 (537)/297/PD5500 Module
    • Fixed an issue in WRC 297/PD5500 analysis with square or rectangular attachment types, which caused errors with the WRC 297 output report

CAESAR II 2014 Version 7.00 Changes & Enhancements (14/17)
Description:
CAESAR II 2014 (7.00) delivers a number of updates for the latest piping codes, numerous stability improvements, and features to benefit your user experience.

Technical Updates

The following technical changes were made for this release, which may affect the numeric results:

  • Added a new equation for calculating expansion stress cases with new SIF and index values to support the 2012 Edition of the ASME B31.3 code.
  • Addressed bend pressure stiffening and changed the longitudinal pressure stress equation, among other revisions, to support the 2012 Edition of the EN 13480 code.
  • Updated the minimum wall thickness equation for ASME B31.8 Chapter VIII to consider the longitudinal joint efficiency (using the Eff input box).
  • Updated the ASME B31.8 code interpretation to use either of the two combined biaxial stress equations for restrained pipe, as referred to in Paragraph 833.4, instead of using the maximum of the two. You can specify this using the Yield Stress Criterion configuration setting in the SIFs and Stressessection of the Configuration Editor.
  • Revised the calculations for SIFs in non-corroded conditions when the CODETI piping code is selected, based on clarification from French Code Committee.
  • Revised the Static Analysis (Load Case Editor) to automatically recommend Expansion (EXP) stress range load cases for better coverage of multiple operating conditions.
  • Provided an option for users to select the allowable corresponding to temperature for that particular Occasional (OCC) load case for B31.3 jobs.
  • Added support for in-line flange check evaluations for MAX and ABS load case combinations.
  • Resolved an issue in Structural Input where the software did not process UNIF values as gravitational multipliers (G loads) after you added theGLOAD command into the input stream. The software uses the gravitational multiplier (G load) value for all UNIF values when you add the GLOADcommand into the input stream.

Interface Enhancements

The following are the new features in this version.

Piping Code and Material Database Updates

  • Updated to support the 2012 Edition of the ASME B31.1 code. This work included material property updates.
  • Updated to support the 2012 Edition of the ASME B31.3 code. This work included a new equation for calculating expansion stress cases with new SIF and index values.
  • Updated to support the 2012 Edition of the ASME B31.8 code.
  • Updated the ASME B31.8 code interpretation to use either of the two combined biaxial stress equations for restrained pipe, as referred to in Paragraph 833.4, instead of using the maximum of the two. You can specify this using the Yield Stress Criterion configuration setting in the SIFs and Stressessection of the Configuration Editor.
  • Updated to support the 2013 Edition of the ASME B31.5 code.
  • Updated to support the 2012 Edition of the EN 13480 code. This work included addressing bend pressure stiffening and changes to the longitudinal pressure stress equation, among other revisions.

  • Added support for ANSI 16.5 2009 metric flange ratings.
  • Added fatigue curves as indicated in the 2013 Edition of ASME Section VIII, Div. 2.
  • Extended the content for the ASME B31.3 code update and B163 to 1400F.

Modeling and User Interface

  • Enabled quick global property changes (such as for temperature and pressure) from the Legend dialog box in the 3D model.
  • Enhanced the Distance command to measure between two points in the 3D model. The distance functionality works either graphically or by entering node numbers, and provides you with a quick way to verify your model.
  • Added a new Global menu in the piping input, which includes the Block commands. These commands are also accessible through the Block Operations toolbar and the right-click context menu from the List>Elements dialog box.
  • Enhanced the Structural Steel Wizard to display units for various input fields, added more tool bar icons, and enhanced input grid usability.
  • Addressed graphics issues.
  • Completed minor usability enhancements based on customer feedback.

Static and Dynamic Analysis

  • Revised the Static Analysis module (Load Case Editor) to automatically recommend Expansion (EXP) stress range load cases for better coverage of multiple operating conditions.
  • Provided an option for users to select the allowable corresponding to temperature for the specified Occasional (OCC) load case for B31.3 jobs.
  • Added support for in-line flange check evaluations for MAX and ABS load case combinations.

Interoperability

  • Added the ability to import multiple supports at the same location from the Import PCF or Intergraph Smart 3D PCF interfaces.

  • Updated the F1 help in the Static Output Processor.
 

CAESAR II 2013 SP4

The following revisions were made for this release:

User Interface/3D Model

  • Fixed an issue with the Insert Element and Reset Plot options. When you opened a job with the List Input dialog boxes closed, and you clicked Insert Element, the software did not open the Insert Element dialog box. In the same scenario, if you changed the model and clicked Reset Plot, the software did not return the model back to its default state. These options now function as expected when the List Input dialog boxes are closed. 
  • Resolved an issue with resizing elements and the Lock Graphics function. If you selected Lock Graphics without resizing any anchor, restraint, or hanger, when you unlocked the 3D model, the software resized the elements to their largest size. Now, the software retains the element sizing when you unlock the graphics on the model.

Analysis/Calculations

  • Updated stress calculations for B31.3 jobs using Occasional (OCC) and Hydrotest (HYD) load case conditions. The CAESAR II development team revised stress calculations for the Sustained (SUS) condition after the B31.3 code committee moved Code Case 178 into the B31.3 code standard. The software now uses the same stress calculations for Occasional and Hydrotest conditions, which reflects the code standard. Note: This change results in different code stress values for jobs that use the OCC and HYD load cases, especially jobs that have significant torsion stresses. (TR-TX-12374)
  • Resolved issues with unit conversions for jobs using the BS 7159 or UKOOA codes when you used a custom units file. The issues resulted in discrepancies in calculations between the Bend SIF Scratchpad in Piping Input and the results in the Static Output. The scratchpad calculations now show the same results as the Static Output. (TR-TX-12342)

Error Checks

  • Resolved an issue during error checking with WRC 297 nozzle identification. The issue, when manifested, caused the software to generate misleading error messages, which also prevented the analysis of the model.

Output Reports

  • Resolved an issue with the Send to Printer option in the Static Output Processor. When you generated a stress report on any analyzed job that used the Stoomwezen piping code and selected Send to Printer in the Output Viewer Wizard, the software did not print the Stoomwezen Approval Certificate. The software now prints the certificate when you select Send to Printer and generate the output report.
CAESAR II 2013 R1 Version 6.10 Changes & Enhancements (11/12)
Description: CAESAR II 2013 R1 (6.10) delivers a number of significant new and extended capabilities to increase productivity, supply the latest piping codes, and improve user experience.

Technical Updates

Updated piping code information for ASME B31.1, B31.3, B31.8, B31.9, and Z662 codes. The ASME B31.3 2010 Edition includes many significant changes, such as the new equation for sustained case evaluation and new stress indexes (It/Ia).

Interface Enhancements

  • Import piping models from Smart 3D to the Piping Input module, using the new APCF interface. This interface saves you data entry time while reducing errors.

 

  • Incorporate the design context of the plant within CAESAR II to make more intelligent re-routing and support location decisions and potentially reduce design-analysis iterations. The ability to import Smart Plant 3D (S3D)/Smart Plant Review (SPR) graphic environment (VUE file) complements the existing capability to import CADWorx (*.dwg) plant models.

  • Export to Microsoft Access format. Using this format, selected CAESAR II results are available in Smart Plant 3D (S3D)/Smart Plant Review (SPR) for easier identification of changes made by the engineer.

 


Productivity and Usability Enhancements

  • Reorganize a model using two new block commands (Invert and Change Sequence).
  • Use line number classifications to make quick edits when performing all block operation selections (such as duplicate, delete, and renumber). This feature is in addition to the already available Graphical and List Select functions.
  • Experience the improved Renumber and Annotation functions.

Performance and Functionality Improvements

  • Increased stability by updating the Isogen module to Personal Isogen Version 8.1.
  • Increased performance by updating the graphics engine.

CAESAR II Version 3.24 Changes & Enhancements (3/97)
Description:

1)

Multiple (3) displacement/force/uniform load vectors have been added. Note that these load cases, called D1/D2/D3 and F1/F2/F3 , may be toggled on the input plot by continuing to press F3 and F5 (displacements cycle through D1 D2 D3 , and then off). The naming of these load cases has also required the renaming of the CAESAR II load combination terms – D1 F1 S1 , etc. must now be called DS1 FR1 , and ST1 . Note that all hanger loads and cold spring forces (from materials 18 and 19) are still lumped into load case F1 , for consistency with previous versions of CAESAR II .

2)

A material data base for piping properties and allowable stresses for many of the piping codes supported by CAESAR II has been implemented. This is invoked by pressing [ALT – M] on the mainCAESAR II input spreadsheet (also at the list option and on the WRC 297 nozzle flexibility spreadsheet). After bringing up the list of materials, a material name can be typed in; matching records are then displayed for selection. Allowable stresses are updated automatically whenever temperatures, materials, and/or piping codes change.

 

Database management is provided from the Utilities option of the main menu. Users may edit COADE provided materials or add their own. Material parameters may be provided for code 0 (represents generic values for any non-specified code) or for specific codes. It is recommended (due to futureimplementation plans) that metals be assigned identification numbers between 100 and 699, while FRP materials receive numbers between 700 and 999. Note that selection of FRP materials from the material database will not currently activate the orthotropic material model in CAESAR II . This must still be done through the use of material 20 (see item 6 concerning this below).

3)

8 character job names are now supported (input files are identified by extension ._A, output files by extension ._P, ._S, etc.). Existing files are automatically recognized and converted to their new format. (See related item 16 below.)

4)

Modifications have been made to allow multiple users working from the same network data directory via the environment variable COADE_USER. This environment variable should be set to a unique 3 character combination (i.e., the user’s initials) for each user working in the common directory. Implementation can be done by adding to the user’s AUTOEXEC.BAT file a line such as:

  SET COADE_USER=TVL

5)

CAESAR II ’s Valve and Flange database now incorporates data files from CADWorx/Pipe . This change provides four advantages:

 

a) Component weights and lengths are more accurate, as well as traceable to specific catalogs, standards, etc.

 

b) Weights and lengths are provided for more components than were previously available in the CRANE or GENERIC databases.

  c) Since CADWorx/Pipe data files are text files, users may easily edit or add components.
 

d) If the user also has CADWorx/Pipe on their machine, the two programs will share the same data files and project specs, enhancing the performance of the bi-directional interface. Gaskets are included for flanged items, so a better fit is provided between the CADWorx/Pipe and CAESAR II models.

6)

The user may now set default values for FRP (material 20) parameters via the configuration/setup. These default parameters may be read automatically from manufacturers data files by toggling through the list of available files, and then pressing [ALT-U] (for Update) on the selected vendor file. Vendor files are recognized by their .FRP extensions; since these are text files, users may create them easily themselves, or vendors may distribute them to their customers.

7)

The UKOOA (United Kingdom Offshore Operators Association) piping code for FRP piping has been added.

8)

The Z183 and Z184 piping codes have been replaced with the Z662 code, which has been expanded to consider calculation of stresses in “restrained” piping.

9)

The ASCE #7 wind code has been updated to the 1995 edition.

10)

The API-610 code in the equipment module has been updated to the 8th edition.

11)

ASME Section VIII Division 2 stress indices and WRC-107 SIF (k , k ) values have been incorporated into the WRC-107 module.

12)

The “Relief Load Synthesis” dynamics module now supports metric (or custom) units.

13)

A number of configuration file default values have been revised in order to improve calculation results or program performance:

 

Changed From To
  BEND_LENGTH_ATTACHMENT=

5.0

1.0

  BEND_AXIAL_SHAPE =

NO

YES

 

FRICT_STIFF =

50000

1.0E6

  FRICT_NORM_FORCE_VAR = 25

15

  FRICT_ANGLE_VAR = 30

15

 

 VALVE_&_FLANGE =

GENERIC

CADWORX

 

Four new directives added to the   configuration file.

   
 

SYSTEM_DIRECTORY_NAME =

user defined, defaults to SYSTEM (note user may now maintain multiple system directories for different projects)  
  UNITS_FILE_NAME = user selected from list (note current units are now set through theconfiguration/setup, not through the units option of the main menu)  
  BS_7159_PRESSURE_STIFFENING=

Design strain or Actual Pressure

 
  FRP_PROPERTY_DATA_FILE=

user selected from list

 

14)

The configuration file can also be password protected in the Installation Directory . This prevents modification of all Computation and Stress Control directives. Subsequent use of the configuration module prevents modification of these directives, unless the password is known. Colors, printer settings, etc. may still be changed by users without the password.

15)

CAESAR II has been modified to accept an optional job name (including full drive and path data) as an argument; the program switches to the appropriate drive and directory, opens the specified job, and goes into input (bypassing the main menu). This allows the definition of ._A files as CAESAR II input files (under Windows 95) and subsequent double clicking on the file name in a Windows/95 explorer window to start the input processor on the picked job file. This also allows CAESAR II to be spawned from other programs, right into a job.

16)

Modifications to CAD interfaces: Intergraph and CADPIPE.

17)

All necessary routines have been checked (and modified where appropriate) to address the “Year 2000″ issue.

18)

A Korean structural steel shape library has been added.

19)

A new spring hanger table has been added (SARATHI).

20)

BS-5500 nozzle flexibilities have been incorporated to complement the WRC-297 and API-650 nozzle connections.

  • Hoop Stress can be computed based on Outer Diameter, Inner Diameter, Mean Diameter, or Lame’s equation.
  • The spring hanger design spreadsheet has been modified to default to a 25% load variation. In addition, the actual hanger load variation now appears in the hanger output reports.
  • A new command (WIND) has been added to the structural steel preprocessor. This allows selective wind loading on an element by element basis.
  • A new key-combination (Alt-D) is available in the input processor to compute the distance between two nodes.
  • User specified coordinates for up to 30 nodes are saved in the input file.
  • The input title page has been expanded from 19 to 60 lines.
  • Automatic node numbering abilities have been added to the spreadsheets of the main piping input module
  • Expansion Joint data bases from IWK (Germany) are provided.
  • Expansion Joint data base from Senior Flexonics is provided.

CAESAR II Version 3.21 Changes & Enhancements (7/94)
Description:
  • Most of the CAESAR II executable modules have been converted from Microsoft 16 bit FORTRAN to WATCOM 32 bit FORTRAN. This has reduced the low DOS RAM requirements of the program from 577k to 475k.
  • The modules converted to 32 bit operation for Version 3.21 are summarized in the following table:
  • Static Stress Computation Module (1)
  • Piping, Buried & Structural Steel Input Modules (3)
  • Piping Error Checker (1)
  • Load Case & Dynamic Input Module (1)
  • All CAD interfaces (8)
  • Neutral File interfaces (2)
  • The software now supports an ESL from a new vendor. This provides CAESAR II with full networking abilities. The program first checks for a local ESL (from either vendor), then for a network ESL.
  • Toward the support for network operations, the data files which are not job specific are now assumed to be located in a SYSTEM subdirectory underneath the CAESAR II installation directory. These data files include: the input listing formatting files (*.INP), the accounting data files, the printer formatting file, the file handler template file, and the various header files.
  • The common factor among all of these files is that they are specific to a company installation, not a particular data directory. Up until Version 3.21, these data files were manipulated by the program (or sometimes directly by the user) in the installation directory. However, many network installations“write protect” their installation directories, making modifications to these files impossible. We have therefore placed these files in a SYSTEM subdirectory to which users should be given complete access.
  • Note that CAESAR II Version 3.21 will be capable of running on a local machine (with either vendor’s local ESL) or on a network (with the network ESL). The changes made to the software enable the same version to be run under these various configurations.
  • An additional spring hanger manufacturer has been added, Carpenter & Paterson, UK.
  • The UBC (Uniform Building Code) earthquake spectra have been added.
  • The B31.5 piping code has been added.
  • The piping code addenda have been reviewed and any necessary changes made to the software. The addenda include revisions for: ASCE #7, B31.1, B31.8, ASME NC, and ASME ND.
  • The SIF scratch-pad from the Miscellaneous processor (Option C of the Main Menu) has been incorporated into the piping preprocessor. This processor includes all of the supported piping codes (not just B31.1 and B31.3 as before) and all of the fittings. Additionally, any changes made to the scratch-pad data can optionally be transferred directly to the main CAESAR II data spreadsheets.
  • Additional changes to the input piping preprocessor include:
    • problem size is now dependent on the amount of free extended memory – the old limit of 400 elements is now upwards of 8,000 elements
    • graphics menus automatically turned off for hard copies
    • optional node number display for supports, anchors, hangers, and nozzles
    • function key map shown on main spreadsheet
    • auxiliary input spreadsheets support help
  • The accounting system has been completely rewritten. This provides a more streamlined interface. Additionally, accounting statistics are now recorded from the stress computation modules (previous versions only recorded the actual matrix decomposition times).
  • The API-617 and NEMA-SM23 reports have been overhauled so that the code compliance when using non-English units systems is consistent.
  • The new Flange Rigidity factor from ASME Section VIII has been added.
  • A new loader (C2.EXE) has replaced the original one (C2.COM). This new loader performs initial startup checks, with diagnostic reporting if necessary, and enables error processing from the Main Menu.
  • The configuration program has been modified to track changes. Users attempting to [Esc] out after making changes are warned that the changes will not be saved.
  • A “graphics viewer” has been added to the file manager. This enables rapid model plotting directly from the file manager of the Main Menu.
  • Additional directives are available to disable the generation of the Table of Contents page, and disable the display of the spreadsheet function key mapping.
