Class
    Foam::fv::explicitPorositySource
 
Group
    grpFvOptionsSources
 
Description
    Explicit porosity 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
            {
                origin  (0 0 0);
                e1      (0.70710678 0.70710678 0);
                e2      (0 0 1);
            }
        }
    }
    \endverbatim
 
Note:
    The porous region must be selected as a cellZone.
