Class
    Foam::fv::explicitPorositySource
 
Description
    Explicit porosity source
 
    \heading Source usage
 
    Example usage, here employing the Darcy-Forchheimer model:
    \verbatim
    explicitPorositySourceCoeffs
    {
        type            DarcyForchheimer;
 
        DarcyForchheimerCoeffs
        {
            d   d [0 -2 0 0 0 0 0] (5e7 -1000 -1000);
            f   f [0 -1 0 0 0 0 0] (0 0 0);
 
            coordinateSystem
            {
                type    cartesian;
                origin  (0 0 0);
                coordinateRotation
                {
                    type    axesRotation;
                    e1  (0.70710678 0.70710678 0);
                    e2  (0 0 1);
                }
            }
        }
    }
    \endverbatim
 
Note:
    The porous region must be selected as a cellZone.
