Detailed Description

Given a displacement moves the mesh by scaling the displacement back until there are no more mesh errors.

Holds displacement field (read upon construction since need boundary conditions) and scaling factor and optional patch number on which to scale back displacement.

E.g.

    // Construct iterative mesh mover.
    motionSmoother meshMover(mesh, labelList(1, patchi));

    // Set desired displacement:
    meshMover.displacement() = ..

    for (label iter = 0; iter < maxIter; iter++)
    {
        if (meshMover.scaleMesh(true))
        {
            Info<< "Successfully moved mesh" << endl;
            return true;
        }
    }

Note

Shared points (parallel): a processor can have points which are part of pp on another processor but have no pp itself (i.e. it has points and/or edges but no faces of pp). Hence we have to be careful when e.g. synchronising displacements that the value from the processor which has faces of pp get priority. This is currently handled in setDisplacement by resetting the internal displacement to zero before doing anything else. The combine operator used will give preference to non-zero values.
Various routines take baffles. These are sets of boundary faces that are treated as a single internal face. This is a hack used to apply movement to internal faces.
Mesh constraints are looked up from the supplied dictionary. (uses recursive lookup)
