Hi all,
I am modeling PCB with a heat source, I want to assign thermal conductivity of PCB as directional dependent i.e Kx in X-direction, Ky in Y-direction and Kz in Z-direction. How to define this in Fluent, if it is required to write UDF then please provide me an example UDF. Thank you in advance

use orthotropic material property instead of constant value. You don't need UDF
