Hi everyone !
I'm trying to study large displacement of 2D model in OptiStruct in order to compare the results with our FE solver !
In my solver, I'm using Saint Venant Kirfchhof behaviour law to resolve Non-Linear Large Displacement problem.
When I perform the same simulation with OptiStruct I find something weird ! Maybe it's due to behaviour law in OptiStuct ... For sure I'm using the wrong one (not SVK one).
My question : Is there is a way, in OptiStruct, to write a subroutine (SVK behaviour law) ... and run the simulation using the user behaviour law (written in the subroutine) ?
Best regards,
