"When I run the simulation with constant porosity and permeability I get a reasonable solution and I can also plot pressure."

This means then that there is something wrong with your CEL. May be it...

If I understand you correctly, you need the porosity and permeability to change independently at each node as a function of local /global pressure.
Then..IF you know the analytical dependence of...

Hello Everyone,

I am reviving this thread after a long time because now I have a situation where an isotropic porosity model will be of great use.
I want to model pin fin heat sinks using porous...

Hello Edmund,

Thanks for your reply.
My question was regarding anisotropic porosity regarding which the CFX manual clearly states that the area available for flow is assumed to be A'= K.A where K...

anisotropic porosity in CFX

Hi,

CFX 13 manual states that CFX does not allow anisotropic porosity i.e. the area porosity tensor is isotropic.
I model microchannels as porous medium and to force the liquid in only one...
