Hello rgpatchi,


In our simulation, we intended to specify a preintegrated membrane stiffness for shell sections instead of specifying isotropic linear elastic material properties. We first calculate the stiffness properties of the shell and then apply them using the "SSPA" "SSPD" and "SSPE" commands, which is corresponding to command lines:


sectype,1,gens,,bandanyuan,


sspa,420626,126188,,4.24713e8,,,


sspd,43.6662,13.0999,,48446.7,,30.6256,


sspe,,8.15102e7,


However, the commands do not work well. Do we make any mistakes using these commands?


Thank you very much!


 


Best regards,
