Cubit 15.8 User Documentation
After a mesh is generated, it is checked to ensure that the mesh has valid connectivity. If an invalid mesh is formed, then CUBIT automatically deletes it. This default behavior can be changed with the following command:
Set Keep Invalid Mesh [on|off]
The current behavior can be viewed with the following command:
List Keep Invalid Mesh
The Jacobian quality metric is also computed automatically to check quality after a mesh is generated. If the quality is poor, a warning is printed to the terminal.
