Making Sense of FEA Node (Grid Point) Stresses | MSC Nastran

When you are working with a structure that is modeled with either plate or solid elements, it is quite common that you may want to look at either the printed output or contour plots of the element component stresses. If this is the case, extra care must be taken on your part to ensure that …

The Best FEA Mesh Transition | MSC Nastran

Mesh transition can be a complicated subject. It may simply be used to refine the mesh in a particular area, connect different element types (for example, a CBAR element to a solid element), or provide transitions required to model the geometry of the structure. Two guidelines for mesh transitions are as follows: Never place a …

The Best FEA Mesh Density for Accuracy and Speed | MSC Nastran

The mesh density in a finite element model is an important topic because of its relationship to accuracy and cost. In many instances, the minimum number of elements is set by topological considerations, for example, one element per member in a space frame or one element per panel in a stiffened shell structure. In the …

Choosing the Right Finite Element | MSC Nastran

MSC Nastran contains a large library of structural elements. In many situations several elements are capable of modeling the same structural effects. The criteria for the selection of an element may include its capabilities (for example, whether it supports anisotropic material properties), its cost (in general, the more DOF an element has, the more expensive …
