Hey everybody,

Has anyone tried to do a CD nozzle transient simulation in the fluid scenario creation app. I have tried several ways and I am not able to achieve correct results (Typically an error appears about negative Temperatures). My questions mainly are on how to correctly give the software a background and input pressure, as well as a mass flow at input. The simulation only runs if I give a timestep of 1e-12, which would mean that the sim itself would take days to complete.

Thank you!
