currently i am writing Master Thesis about homogenization of composite material and i would like to make a simulation of behaviour of RVE in HyperMesh (solver OptiStruct). In this forum i found information that i should use PERBC card but i can't find this card in student version (i have 2017 and 14 version).
Does somebody have tutorial how to use PERBC card or is it possible to apply periodic boundary condition in student edition without this card?
I make dof=0 in normal direction on three face and i want to make opposite faces flat and parallel to blocked faces.
I have 3d model with tetra mesh.
