We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Rob, thanks for the fast reply!

I am quite new to ANSYS in general, so I am not certain I understand your response correctly. My idea was to create a UDF that would change the sample outlet surface from wall to pressure outlet after a set amount of time after starting the simulation. But since I am new I don't know if that's even the correct approach. And regarding your response, would a negative value make it cancel out the incoming flow creating a boundary for the time the sample is supposed to be closed in the beginning?
