NX Nastran Model Checks

Understanding the numerical conditioning of your finite element model is critical to ensuring high-quality results. This document discusses six essential NX Nastran model checks: the grounding check, the rigid body mode check, the weight check, the element quality check, the stiffness singularity check, and the residual check. These quality measures should be checked and monitored throughout the design cycle to help build confidence in your finite element model and in the results that you generate.
