Help:something about boundry condition
I have a problem: I want the boundry condition of a face to be a wall from 0 to 1s while the boundry condition to be a pressureinlet for 1s to 2s.(it's a 3d mesh)
Can I use udf to do this thing?
Thank you in advance.

You could write a UDF that run every time step, and read the flow time. when you want to change the boundary then change the boundary. Maybe use the define adjust macro. I have not written UDF for several years and have forgotten the details. But I think this option is possible.
