Hi,



I want to add a cubic heat source in a room. I think I should use fvOptions
but i am a total beginner and am unable to find any mention of it in the userguide.
Could someone help me get started and maybe link some tutorials having such a heat source.

You need to define a cellZone,(e.g using topoSet) and add something along these lines. Instead of all you need of course add your cellZone.
