i still didn't manage to solve the problem

Hey,
I still didn't manage to run the pressure-driven flow. It's not a mesh problem. I ran checkMesh. The simulations is running, however the results are shit. Ridiculous high values. And the time...

Thanks

Thanks for the quick reply. However I would like to calculate the massflow at different pressure-differences! Doing it the other way round would mean a lot of calulationtime. There must be a way to...
