The meshing of a solid model consists of two basic phases. In the first phase, the mesher places nodes on the boundary. This phase is called surface meshing. If the first phase is successful, the mesher starts the second phase where it creates nodes in the inside, fills the volume with tetrahedral elements, and places mid-side nodes on edges.
Failure can occur in either of the two phases. When the meshing of a part fails, SimulationXpress opens the mesh failure diagnostics tool to help you locate and resolve meshing problems. The tool lists the faces and edges that caused the failure. To highlight a face or an edge that failed to mesh, select it from the list.
