zheng zhou New Member Zheng Zhou Join Date: Mar 2021 Posts: 1 Rep Power: 0	Hello,everyone. I am a green hand of Fluent. Recently, I got stuck in defining the species diffusivity.There is no option to define the diffusivity in the porous zone. Can anyone teaches me how to set the value of diffusivity in a porous zone (I have written a UDF to define the diffusivity)?
