Class
    Foam::externalDisplacementMeshMover
 
Description
    Virtual base class for mesh movers with externally provided displacement
    field giving the boundary conditions. Move the mesh from the current
    location to a new location (so modify the mesh; v.s. motionSolver that
    only returns the new location).
 
    All mesh movers are expected to read the dictionary settings at invocation
    of move(), i.e. not cache any settings.
