How to do Super element analysis

[Venkat133]

Hi
I have to do the static analysis in nx nastran for a big model. So i solved the model I got more stresses on one plate on the model. So iam trying to reduce the values by adding stiffness. While solving I came to know that 'by doing super element analysis it is very easy'. I did the model with sol super element analysis for that frequencies and mode shapes are matching for both normal and super element analysis but in static analysis stresses and disp are not matching with original model. Could u tell me the procedure to do the sol 101 super element analysis

You can find help in MSC's Linear Static Analysis User Guide, it applied to NX Nastran as well. If you want detailed help, post your bdf.

If your normal modes analysis matches, but your static analysis doesn't, you might be forgetting your "P2G=PAX" line.
