Darcy-Forchheimer law porosity model, given by:
![\[ S = - (\mu d + \frac{\rho |U|}{2} f) U \]](form_0.png)
where
 | = | Darcy coefficient [1/m2] |
 | = | Forchheimer coefficient [1/m] |
Since negative Darcy/Forchheimer parameters are invalid, they can be used to specify a multiplier (of the max component).
The orientation of the porous region is defined with the same notation as a co-ordinate system, but only a Cartesian co-ordinate system is valid.
