Hi Everyone,
Does anyone know how to specify an anisotropic diffusivity tensor for the fluid (not a user-defined scalar)? All I can find is the DEFINE_DIFFUSIVITY macro and since it only returns one real, I'm not sure what to do. Thanks a lot! |

I have the same problem, what I can think of is to solve the species balance equation as an UDS and then define directional diffusivity (anisotropic) using DEFINE_DIFFUSIVITY.
please let me know if you find any way. |
