Hi, I want to chang one boundary type into another boundary type during computation automatically by star-cd,for instance,changing the pressure boundary into wall bounary, is there anyone to provide some specific help or suggestion?

thanks a lot!

In transient run, you can use load steps (TRANSIENT panel: GUI - Modules=>transient) to set up: 1. put button Initialize; 2. in load step one, you specify a boundary as pressure, save this load step; 3. then set up load step 2 with boundary as wall, save this load step; 4. Load step range from 1 to 2, apply, write problem file, and you get it.

you can use the subroutine to change boundary type
