Hi

 

Assuming you use user integrated shell formulation (so using SSPX commands)

Define SSPE (there might be some simple expressions that approximate it, say ~ constant*G*thick.) as it is needed for membrane + bending analysis (if it was only membrane option, then SSPE is not needed - see help manual).

 

Perhaps other forum members have some further feedback.

 

All the best
