Class
    Foam::TopologicalMeshObject
 
Description
    MeshObject types:
 
    - TopologicalMeshObject: mesh object to be deleted on topology change
    - GeometricMeshObject: mesh object to be deleted on geometry change
    - MoveableMeshObject: mesh object to be updated in movePoints
    - UpdateableMeshObject: mesh object to be updated in topoChange or
        movePoints
    - PatchMeshObject: mesh object to be additionally updated patch changes
