How tensor parameters to be entered in CFX-pre?
 
hi
I m trying to simulate Flow through porous media and I'd enter the permeability parameter from a tensor.But I do not know how?:confused:
(ansys CFX-pre/defalt domaine/porous domaine/porosity setting/permeability)
(for Simulation of Vacuum Assisted Resin Transfer Molding process)

ANSYS CFX presently allows only K(permeability) to be isotropic ( Ansys CFX help):eek:
