FE based entities including shell mesh, solid mesh or any 1D element (RBE2, RBE3, and so on) not associated with geometry are not handled in BasicFEA.  

Models containing composite material data and ply based information are not supported in BasicFEA.

Models with contact surfaces created in HyperMesh via CSURF definition are also not supported in BasicFEA. The mechanism for basic contact modeling can be employed via entity set, which is available.
