Hello,
I have written efficiency expression in CFX pre. It will give me a value of efficiency at each step. Efficiency expression I have written in CFX by: Efficiency= (((P02/P01)^(0.4/1.4))-1)/((T02/T01)-1) P01= massFlowAve(ptotstn)@R1 Inlet P02= massFlowAve(ptotstn)@R1 Outlet T01= massFlowAve(Ttotstn)@R1 Inlet T02= massFlowAve(Ttotstn)@R1 Outlet But now I want to stop calculation once it reaches to certain convergence criteria. This need to record efficiency as a variable of iteration step. Is anyone know how to define a variable expression in CFX pre??? Thanks in Advance...!!!!

I know that.
But how to provide Eff as a function of iteration? As by defining expression it is just take value a single step at a time.
