Yes I solved the initial problem by adding the flow volume. I tried to achieve vacuum conditions by putting air into the flow volume, but with a pressure of 1E-7 Pa. I guess thats the reason why the simulation is still failing, because air flow simulation under such pressure conditions lead to extremely small currents, which might be to much calculation effort.
Do you have any tipps for me how I could aproximate vacuum conditions?
I’m a little confused why vacuum conditions are not supported. It’s the most simple case for calculating energy transport processes, isn’t it?
