Hello forum users,
I am curious about this question: user-defined element in OptiStruct?
Does OptiStruct support this kind of user subroutine like Abaqus UEL?
What I want to do is to define a special element's stiffness matrix for static analysis and I have the version in Fortran for Abaqus UEL.
No idea and resources can be found online about OptiStruct user-defined element?
Any answer is helpful and much appreciated.
Thank you!
