Class
    Foam::DeletableMeshObject
 
Description
    MeshObject types:
 
    - DeletableMeshObject:
        mesh object to be deleted after any mesh change
    - MoveableMeshObject:
        mesh object to be updated after mesh motion otherwise deleted
    - DistributeableMeshObject
        mesh object to be updated after mesh redistribution or motion
        otherwise deleted
    - TopoChangeableMeshObject:
        mesh object to be updated after mesh topology change,
        mesh-to-mesh mapping, redistribution or motion otherwise deleted
    - RepatchableMeshObject:
        mesh object to be updated on patch or topology change,
        mesh-to-mesh mapping, redistribution or motion otherwise deleted
    - PermanentMeshObject:
        mesh object to be updated on patch or topology change,
        mesh-to-mesh mapping, redistribution or motion and never deleted
