Hi all,

I am working on modeling heat transfer and fluid flow in a plate-fin heat exchanger (aluminum structure with separate channels for air and steam flow). Air flows through the triangular channels and steam through the rectangular channels.

I have successfully (I think) created and meshed the geometry, and have defined named selections for all inlets, outlets, domains and interfaces. However, when I open setup, I receive a series of errors of the following type:

Warning: materials in neighbor cell threads (11 and 9) of
interior zone 1 are of different types (air and aluminum).
This problem MUST be fixed before solving!

After some digging, I noticed that fluent seems to have defined an incorrect face zone, shown below.

Is this what is causing my problem? Can I remove it (or separate the cells that make it up and merge them with their respective correct zones)? Any help would be greatly appreciated and I can provide any more info as needed!
