my first Natural Ventilation case with OpenFOAM
Hi to all!
I'm a newbie of CFD. I'm a student of Building Engineering/Architecture and I'm trying to simulate the natural ventilation of my building considering the wind and buoyancy effects using OpenFOAM. What do you think would be the best settings for boundary conditions? My mesh is like a box, with the faces not oriented in direction of the wind, because I need to simulate different direction cases. I'm trying to find a good solution for setting fields U, p and p_rgh for my boundaries top, ground/building, north, south, east and west, but every time something goes wrong... someone can give me a hand? :confused: thankyou PS: I start from hotroom case of buoyancySimpleFoam tutorial. Is it right? |
Until now, I tried setting east side of my volume as inlet, the building and ground like a wall and top/west/north/south like outlet. The resulting U fields looks like:

well, I changed the value of pressure for both inlet and outlet conditions to fixedValue uniform 101325. Now the simulation run, but I can't understend very well the differences between p and p_rgh. It's correct to use the same settings for both pressures?

hi to all.i'm a newbie of CFD.i'm try to run one case in tutorial that can simulate ventilation in simple room,so wich one case can be use?? and how i can run it
any refrence,guid,idea can help tnx |
