boundary conditions

February 23, 2005, 02:32

I am using premixed combustion model. I would like to change the boundary condition of progress variable in one of the wall. How can I do so I cannot use UDF since in wall you can define any profile. Z

Also one more question. In the geometry investiaged I have velocity inlet and pressure outlet boundary condition. In the velocity inlet I have specified progress variable to be 0 and in case of pressure outlet (backflow progress variable 1.0). This means this boundary conditions of c=1.0 will be applied only when there is back flow. How can I make it c=1.0 whether there is backflow or not. Z
