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.

Re: CFX- Turbo grid - Calculate the average Static

dear my problem is how to define the boundary condition well,now i set the mass flow rate for inlet and p-static at outlet(p-static=1atm),please what approperiate BC for axial flow water turbine kaplan if the net head is 40m and mass flow in about 116 meter cube/s.also how to present av static pressur is a presssure at required location denote to static pressure.or there is another method to calculate av static pressure
