Hi all,

I am trying to define a permeable wall. It is a simple cylindrical pipe in 3d. I need to have the wall boundary condition to hook my udf, but I also need the fluid to go through the wall. Therefore, I wanted to use the porous jump. However, I realized I need the interior face between 2 fluid zones to set my porous jump boundary condition. Is there any other way to do it?

I can set the interior of fluid as porous jump, but it can't converge due to the existence of the wall I believe.

Any help would be great! Thank you!
