Permeability depent position in openFoam?
 

Hi guys, I am modeling a porous medium in OpenFOAM and I need to know if is there a way to set de permeability as a function of position?. I am adding the source term in the fvoption file. In some forums, guys recommended using the swak4foam nevertheless, I haven't found an example to do.

I would appreciate your answers.
