If you don't need to know what happens inside the walls they may be threaten as boundary conditions. You have to specify what should happen at the upper and lower boundary of your air column. Free inflow and outflow? Forced convection? Something else? This has to set with a boundary condition too.

Greetings to all!
@mikestunna: Please don't write questions inside images Since you are asking questions on a public forum, please keep in mind that the objective is that when people help you, others can be helped too in the future. More details are given at the thread: How to give enough info to get help Transcribing what you wrote on the paper: Quote:
As for setting up the case, if you are using OpenFOAM 2.3 or newer, I'm unfortunately unable to help much in this, because there was a critical change made in OpenFOAM that I still haven't managed to find the time to figure out how it can be properly implemented in the tutorial for the "planeWall2D". My advice is to take the tutorial case "heatTransfer/chtMultiRegionFoam/multiRegionHeater" as a base for your case and remove the parts that you don't need. In other words, gradually construct your case based on this tutorial case. Best regards, Bruno
