Currently I am using NX 8.5 (advanced simulation with sol 103_response simulation). I try to find the mode shapes and FRF for a flat panel with three simple boundary condition cases (which all the edges either are clamped,simply supported or free)
1. What are the BC condition for free case since if i put all the edges free (all the 6 DOF are free), the simulation cannot be run?
2. Any advices/reviews should I consider/check again to increase accuracy since my FEA results for clamped and simply supported are different with the theoritical results? ( I have taken consideration on the material choice/properties and refining the mesh)
