Class
Foam::PatchCollisionDensity
Description
Function object which generates fields of the number and mass and rates
thereof of collisions per unit area on all patches. Can optionally take a
minimum speed below which a collision is not counted.
Example usage:
\verbatim
patchCollisionDensity1
{
type patchCollisionDensity;
minSpeed 1e-3;
}
\endverbatim
