Hey @CFD_Friend, i already found the problem. The density was not right. But now the question, why did this happen, with a density being to low in the domain. For the openings i selected reference Temp. 25°C. Did CFD calculate the density of the air, which is coming is from the opening? Being of  higher density it would "fall" in my domain. Is this the right assumption?
