Need expression result at every time step in cfx-post

Vimal Chaudhari · October 18, 2022, 08:44

I am working on turbine. I need to calculate average torque of turbine at every time step. So i have set "expression" of torque as "torque_y()@turbine" in "CFX-Pre" and in "output control" set "Monitor point" 1 as expression. And i have completed solution. My question are
(1) How can i get the value of torque at every time step in excel file or csv file in the "CFD-Post" ? Please guide me step to find the value of torque at every time.

I can find torque in "expression" tab but it is for a selected time step only. I need torque at all time step collectively at a time.

Open CFX Solver Manager, open the case, look for your Monitor Point in the list of user points. Once found and selected, you can export the plot to csv.
