Meshing

Prior to running an Autodesk Simulation CFD analysis, the geometry is broken up into small pieces called elements. The corner of each element is a node. The calculation is performed at the nodes. These elements and nodes make up the mesh.

In three dimensional models, most elements are tetrahedrals: a four sided, triangular-faced element. In two dimensional models, most elements are triangles:

Terminology

Solution accuracy depends on a good mesh, and Autodesk Simulation CFD automates much of the mesh creation process to help you create a good mesh for your simulation.
