I am trying to model a simple plate heat exchanger between air and water and a solid plate in between. However i keep getting this warning:


Warning: zone of type interior found between different fluids!
Material of cell zone 7 is air, while material of cell zone 6 is water-liquid.
This will adversely affect the solution.
Please correct the setup.


Please help

If you can post a picture of the mesh it would be helpful to give a more exact answer.

What I assume is happening is that you have an interface between two fluid domains. The interface was read into Fluent as "Interior". Find this interface, right click, and change it to a "Wall". This should solve your problem.

To avoid this in the future you can name the interface in meshing as "Wall" and Fluent should automatically set it to a wall as it reads the mesh.
