Hello,

I am attempting to analyse the attached pressure vessel for maximum membrane stress in the thicker shell sections at the saddle locations. I have successfully set-up and run the simulation to calculate maximum stress, however I specifically want to analyse for Membrane Stress?

After some research it appears I need to convert the sections to analyse for membrane stress to shell elements to enable me to select membrane stress post run. Is this correct? Are there any guides to doing this as I am struggling.

Many thanks for any help.
