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; } }

Set displacement field from displacement on patch points.
Modify provided displacement to be consistent with actual boundary conditions on displacement. Note: resets the displacement to be 0 on coupled patches beforehand to make sure shared points partially on pp (on some processors) and partially not (on other processors) get the value from pp.
