hello every one,
i'm a new OpenFoam User, i actually use OpenFOAM-v2006 on windows with a graphic user interface for my master thesis

i want to do a natural ventilation simulation in a house exposed to solar radiation

i began with simulating an external flow over building with solar load ( with BuoyantSimpleFoam Solver) to get the external temperature but it gives very high temperature ( about 500 K) which is not reasonable. is this because there is no radiation model ? know that it took 40000 iter to converge, is this normal?

then i switched to ChtMultiRegionSimpleFoam with two Region solid and fluid but it doesn't work it crashes from the start

my questions are:
- how to simulate this type of cases to get reasonable temperature.[CENTER]
- which solver to use for this case
- did ChtMultiRegionSimpleFoam support Solar load on OpenFoam v2006 (june 2020).
- if you have any clue or tutorial that can help me for solarload application

please help i'm lost i can't find any tutorial or a paper for this.

please find attached some pictures of my case ( with BuoyantSimpleFoam) and a zip file containing related file to Boundary conditions
Regards
