maldc New Member Marco Join Date: May 2024 Posts: 1 Rep Power: 0	Hello everyone, I am simulating atmospheric flow around a mountain with buoyantFoam solver [openFoam v10] considering International Standard Atmosphere gradients for pressure and Temperature. With a fixedValue of velocity at the inlet for the wind (I can provide more info if it is necessary, for now i would like to know if someone has been through someting similar). The thing is, at step time = 0, the boundary conditions and initialization seem correct but then (deltaT is 0.001) the internalField of Temperature becomes exactly uniform with a value of 290K. Anyone has a hint what can cause such a big change in the temperature domain?
