Udf condition

      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

      Please can you elaborate?

        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

      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.
