Porous zone definition based on cell zones.
Porous zone definition based on cell zones and parameters obtained from a control dictionary constructed from the given stream. The orientation of the porous region is defined with the same notation as a coordinateSystem, but only a Cartesian coordinate system is valid.
Implemented porosity models:
powerLaw (C0 and C1 parameters)
![\[ S = - \rho C_0 |U|^{(C_1 - 1)/2} U \]](form_0.png)
Darcy-Forchheimer (d and f parameters)
![\[ S = - (\mu \, d + \frac{\rho |U|}{2} \, f) U \]](form_1.png)
Since negative Darcy/Forchheimer parameters are invalid, they can be used to specify a multiplier (of the max component).
The porousZones method porousZones::ddt() mirrors the normal fvm::ddt() method, but accounts for the effective volume of the cells.
