Default Diffusion tensor as an input in fluent
Posts: n/a
Hi Fluent users

Is it possible in fluent to input diffusion tensors at the cell centers or face coordinates in ANISOTROPIC porous zones? Instead of a constant D, I'm wondering if there is a way to input a tensor (2d in the first attempt) to the solver. At this time, lets assume that i somehow have the tensor information either at the cell centers or at the faces?

I am aware that fluent can do this. Is it through a UDF?
