Hey guys I need your help.
I am working on a natural convection case and am looking at a building with openings in the walls and ceiling. The air in the building/room is heaten up by a heat source implemented via fvOptions. So far so good, this works fine. The problem I have is that there is no transport between the air in my room and the air outside of it. Whether U or T seems to change. I don't really know which boundary condition I should set for U at the coupled patches. (Air_to_Umgebung, Umgebung_to_Air) Code:
Air_to_Umgebung { type compressible::turbulentTemperatureCoupledBaffleMixed; value $internalField; Tnbr T; kappaMethod fluidThermo; } Any help or tip is appreciated ![]() Attached a small picture (colouring according to U) Green=air room Blue=air outside Was using noSlip as boundary condition, don't ask me why :/ zeroGradient isn't working either (temperature blows up) |
