Hi all!
I am trying to build a solver for simulating the flow inside closed room.
i guess, i have to use an incompressible flow solver,with turbulence enabled.(steady or unsteady).

Somebody, please suggest me a solver on which i can build my problem specific solver.

cheers!!

Hi Cruiser,

If your problem is isothermal, then simpleFoam is what you need.

Hi,

you also can use bouyantSimpleFoam or with radiation: bouyantSimpleRadiationFoam.

I got many good experience with both solvers.

Bye
Tian

Hi!
Thanks for the replies!
surely, my problem is isothermal.
but i am afraid, the compressible solver may take longer to converge,if i use buoyantSimpleFoam.
there is no radiation either in the problem.
should i build a solver from turbFoam?

Hello Cruiser

Looking at what the buoyantSimpleFoam tutorials, it seems like a good solver for your case. If you run the tutorial hotRoom or hotBox, it will converge in short time (few minutes on standard workstation/PC).

If you have already managed to run the simulation, I would like to know the paramters you used. I am having trouble running a similar ventilation case. Its not converging. Kindly help if you can.
