  24 Class
  25     Foam::surfaceSlipDisplacementPointPatchVectorField
  26
  27 Description
  28     Displacement follows a triSurface. Use in a displacement fvMotionSolver
  29     as a bc on the pointDisplacement field.
  30     Following is done by calculating the projection onto the surface according
  31     to the projectMode
  32     - NEAREST : nearest
  33     - POINTNORMAL : intersection with point normal
  34     - FIXEDNORMAL : intersection with fixed vector
  35
  36     Optionally (intersection only) removes a component ("wedgePlane") to
  37     stay in 2D.
  38
  39     Needs:
  40     - geometry : dictionary with searchableSurfaces. (usually
  41       triSurfaceMeshes in constant/triSurface)
  42     - projectMode : see above
  43     - projectDirection : if projectMode = fixedNormal
  44     - wedgePlane : -1 or component to knock out of intersection normal
  45     - frozenPointsZone : empty or name of pointZone containing points
  46                          that do not move
