Hello everyone,I have a model. The inlet boundary is pressure which is changing. Now I want to know the outlet pressure by simulation of CFX. The outlet condition is connected to a throttle valve. So, how I should set the outlet boundary condition?
Thank you for helping me to solve this problem.

If you want the outlet pressure then you must know the flow rate. So use a massflow outlet.

on the first step (in my opinion) you can make static pressure 0 Pa on the outlet and define a plane before outlet to determine pressure

But the outlet pressure is 0 because that is what you defined it to be. So why do you need another plane to give you an outlet pressure value?
