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.

Hi Cruiser, If your problem
Hi Cruiser,

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

Hi, you also can use bouyan

you also can use bouyantSimpleFoam or with radiation: bouyantSimpleRadiationFoam.

I got many good experience with both solvers.

Hi! Thanks for the replies!
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 wh
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.
