FEA Modeling Guidelines | MSC Nastran

Finite element modeling in many ways is more like an art than a science since the quality of the results is dependent upon the quality of your model. One of the more common errors that a beginning finite element analyst makes in modeling is to simply simulate the geometry rather than to simulate both the …

Taking Advantage of Symmetry in FEA | MSC Nastran

When you think of a symmetrical structure, you most likely think of a structure that has one or more planes of reflective symmetry. Although there are other kinds of symmetry available in MSC Nastran, reflective symmetry is the only type that is discussed in this section. MSC Nastran also provides a series of special solution …

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 …
