Boundary change problem
 
can boundary vary from one type to another? for example,when I running star, can I change the model's boundary from inlet to wall,or some other similarityly change? thank you

Do you want to change boundary types during a running simulation?

If you're using STAR-CD, you should be able to do this using load steps. I don't know about STAR-CCM or CCM+.

Details are provided in the Star User Guide. See Chapter 8 - Analysis Controls for Transient Problems.

you can use subroutine to change the boundary type.
