Basic FEM Checks in NX
Finite Element Model (FEM) checks are an important part of finite element analysis. They reduce the chance for incorrect results and improve project eﬀiciency by reducing solution errors. Model checks include, but are not limited to, mass/CG checks, physical property/ material checks, element quality checks, grounding, stiﬀness, and applied load/reaction force balance. This document explains basic techniques for checking a model at each step of the modeling process in NX.
