The independant analysis modules in CAESAR II are meant to enhance the capability of your pipe stress products, but sometimes the load case import tool doesn't work to import loads from an existing C2 file.  Other odd errors may appear from these tools that this solution will fix. If you ever come across odd errors, here's a quick method to get the modules working again.  


Go to configuration settings, on your home screen. 


Go to your Miscellaneous Options tab.


For the Memory Allocated value under "System Level Items," set this value to 512.


Save your changes on the upper left hand corner.


Now, try the analysis modules again, to see if this fixes the problem.
