Hello
I have a fluid region and a porous region and I want to interface a boundary condition between these two regions. How can this be done?
I once considered these two as walls, but the interface mesh was disabled in Fluent

In meshing name the face as "interface" and re-read mesh into Fluent. This will initialize the face as and interface between the two fluid domains.

I did this before, but after checking the mesh, it shows me the error two adjacent cells zones

Ok, I tried a set-up and what worked for me was naming the interfaces not as "interface". In my case I used "PorousZoneIn" and PorousZoneOut". In Fluent, assign these two faces as "internal". That should give you what you're looking for.

Let me know if it works!
