Hi all,
I am just reposting my question. Glenn, well I look over those files and I discovered that the settings were not good: The problem is a room with a fire (the fire must be set as a volume that is releasing 62 kW). I defined 1 domain this is the whole room – and it is a fluid zone; in this domain I created a solid subdomain which was releasing 62 kW,… well no wonder that I had just conduction. My question is how to define a fire like a certain volume which is emitting this heat? Should I create 2 fluid doamains? Any suggestions are welcome. Regards, Ioana |

Hi Ioana,
There are a number of ways of doing it. You could use one fluid domain, and a wall boundary patch with a heat flux; you could specify a heat source in a subdomain; you could even use a proper combustion model. Depends what you are trying to model exactly. If you want the simplest approach then putting a heat flux on a wall patch would be the easiest way. Glenn |
