Defining porosity using Power law Porosity could be also modeled by the so called Power lawFor each cellZone the following is defined in the file system/fvOptions : type powerLaw; powerLawCoeffs { C0 0.5; C1 2.0; } The source term is(17.8) so the resistance is – in contrast to the Darcy law – isotropic, not directional.
