FEM3D
Files Describing a 3D Finite Element Model


FEM3D is a data directory which contains examples of 3D FEM files, which define a 3D finite element model.

The FEM format is a simple dataset of several files that can be used to describe a finite element model.

The finite element model might include the following files:
