teopetre is on a distinguished road
I want to simulate an unsteady pipe flow in a duct whose outlet is closing during the flow, such as a vane, or a photo diaphragm. Through which macros could I describe in UDF the changing of boundary condition, from pressure outlet to wall? I'm interesting in knowing if it is feasible comparing to a dynamic mesh method.

Thank you very much!
