Inlet residuals fluctuating

Hey guys,
Right now Im trying to simulate the whole car and got a mesh I was happy with. But after checking the residuals I noticed, that the inlet residuals arent anywhere near covergence, so I stopped the simulation.
Other residuals are looking fine, so I wonder what went wrong during pre-processing.

Hello Team StrohmUndSoehne,

just wanted to let you know that I’m currently trying to find out the reasoning behind this. Anyway since the residuals and the results in the post-processor are looking good I would for now trust the results and you can continue with your development.

Best regards
Sebastian
