Hi, 

is it possible to stop the effect of a wave pressure at the inlet after a chosen dt but with the simulation always running?

Thank you 

[Rob]

Please can you elaborate?

[Marti]

I have a time based simulation, my inlet is a pressure inlet defined by a udf (sine wave). I want to study only a few wave cycles and see how they propagate

 

[Rob]

OK, and after some time the boundary pressure is constant? Assuming that's the case have a look at DEFINE_PROFILE and IF statements. It's also possible via Expressions within Fluent using much the same approach.

Yes, thank you
