I would like to model a structure (something like a camping tent) made of beams for the frame and membrane elements for the membrane. Then I would like to apply a pressure to simulate a pressure difference between the inside and the outside of the structure. The problem is that I can not apply a pressure on the membrane elements on Nx Nastran. Am I right? There is a workaround for that?
I know that ABAQUS allows the application of pressure to membrane element using the adaptive automatic stabilization. There is an option of this kind in Nastran. I am using SOL 106 (Nonlinear Static)
