Class
    Foam::dynamicFvMesh
 
Description
    Abstract base class for geometry and/or topology changing fvMesh.
 
    Supports optional update controls that may be used by custom solvers:
    \table
        Property | Description                              | Required | Default
        updateControl   | See time controls below           | no  | timeStep
        updateInterval  | Steps/time between update phases  | no  | 1
    \endtable
