24 Class
25  Foam::motionSmoother
26 
27 Description
28  Given a displacement moves the mesh by scaling the displacement back
29  until there are no more mesh errors.
30 
31  Holds displacement field (read upon construction since need boundary
32  conditions) and scaling factor and optional patch number on which to
33  scale back displacement.
34 
35  E.g.
36  \verbatim
37  // Construct iterative mesh mover.
38  motionSmoother meshMover(mesh, labelList(1, patchi));
39 
40  // Set desired displacement:
41  meshMover.displacement() = ..
42 
43  for (label iter = 0; iter < maxIter; iter++)
44  {
45  if (meshMover.scaleMesh(true))
46  {
47  Info<< "Successfully moved mesh" << endl;
48  return true;
49  }
50  }
51  \endverbatim
52 
53  Note:
54  - Shared points (parallel): a processor can have points which are part of
55  pp on another processor but have no pp itself (i.e. it has points
56  and/or edges but no faces of pp). Hence we have to be careful when e.g.
57  synchronising displacements that the value from the processor which has
58  faces of pp get priority. This is currently handled in setDisplacement
59  by resetting the internal displacement to zero before doing anything
60  else. The combine operator used will give preference to non-zero
61  values.
62 
63  - Various routines take baffles. These are sets of boundary faces that
64  are treated as a single internal face. This is a hack used to apply
65  movement to internal faces.
66 
67  - Mesh constraints are looked up from the supplied dictionary. (uses
68  recursive lookup)
