Hello,

I am analysis multiphase flow in a charging hood and duct of a basic oxygen furnace. Two phases are air and dust particles respectively. My first query is that I need to give total pressure zero at inlet and velocity at outlet to be 43m/s. But the problem is at outlet their is no option for velocity outlet.

Secondly, a warning is shown in the command window which says "flow boundary zone 6 is adjacent to a solid zone 3. This problem must be fixed before solution can proceed."
It would be very helpful if any one of you can help me out.

You could try defining it as a velocity inlet but -43 m/s velocity
