Hi Dia!

you have not described your problem,what u have done untill now?What u wants to do? Where u want this pressure?

Still if u need avg static pressure on any boundary,u need to get it through Tools>function calculator in CFX-Post. Use function:Massflowavg,Variable as Pressure& location is your required Boundary.

with best regards, Kumar.
