Dear All,


Altering the hotRoom tutorial model (tutorials/heatTransfer/buoyantPimpleFoam/hotRoom
) to conform to my own mesh I encountered an error that I do not understand. The output is asking me for radiationProperties while these dont have to be present in the turorial file, and when i add such a file another error appears. Can somebody explain what I am doing wrong? I am running openfoam esi v2112 and i am a beginner so maybe (hopefully) it is obvious. When requested I can send my total working file in a zip or something. Here is the error when I run my code:



// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

Hi Jojell,

The error is not related to radiationProperties, it occurs when the solver is about to start the time loop. You can see that by comparing your log file with the log file of the original hot room tutorial.

My best bet would be that something is wrong in your boundary conditions, but it's hard to tell you more without having more details about your case.
