24 Class
25  Foam::PatchCollisionDensity
26 
27 Description
28  Function object which generates fields of the number and rate of collisions
29  per unit area on all patches. Can optionally take a minimum speed below
30  which a collision is not counted.
31 
32  Example usage:
33  \verbatim
34  patchCollisionDensity1
35  {
36  type patchCollisionDensity;
37  minSpeed 1e-3;
38  }
39  \endverbatim
