Porous media resistances using 2D axisymmetric swirl
 
Hi CFD-community,
We are trying to simulate a highly anisotropic porous media using the 2D-axisymmetric swirl option and defining the porous media by the use of a cell zone condition.

Because of the high anisotropy our viscous resistance tensor (used for Darcy's law) of the porous media hasn't only elements in his principal diagonal. The elements of this principal diagonal are easily entered in cylindrical coordinates (as we understood, Fluent is automatically working with cylindrical coordinates using a 2D axisymmetric approach).
Is there a possibility to enter the entire viscous resistance tensor?

Because of the low Re the inertial resistance tensor isn't needed.

Thanks a lot for your help!
