Hello, dear users. I have a problem with Switching the boundary conditions. There is a chamber with two inlets and one outlet, and I want to simulate a single-phase time-dependent fluid in the chamber. In a time interval (0,t1), fluid enters the chamber through inlet one, and in (t1,t2) fluid enters through inlet 2. how can I switch the inlets in the transient solution. I have attached a schematic photo. Thank you

Well, you should be able to specify time-dependent functions as user-defined boundary conditions in your time-dependent problem. For example, define the functions of time you need under Component --> definitions --> functions and then enter those functions where you would specify your inlet BCs. Have you already tried that?
