Hello OpenFoamers,

i am using the buoyantBoussinesqPimpleFoam solver for my simulation.
I do have a tank, in which is water at 20°C.
The tank has got a hot wall which i initialised with a fixed temperature 50°C.
But after setting my case up my hot temperature at the wall isnt going into the cold water!
I did use the hotRoom tutorial as baseCase.

Does someone know wich properties have to be set, that the wall and the water are "communicating"?

I tried to set different initial values for alpaht, nut, epsilon... but there isnt a heat flow to see.
Also i didnt manage to set externalWallheatFluxTemperature, but i think thats because it isnt usable for this incompressible solver?

I hope somebody can point me into the right direction!

Regards
GerHan
