Question:
I have a transient result file and I want to calculate the torque using the CEL torque function from cfx5post. I noticed that the torque is calculated using the pressure from the current time step. How is it possible to make the torque function to use the timeaveraged pressure (Absolute Pressure.Trnavg) in order to calcute the timeaveraged torque?
Answer:
Steps to calculate the timeaverage torque in CFXPost (Example axial rotor stator tutorial)
1. Create an expression for myTorque (Torque_z()@R1 Blade × Number of Blade)
2. Create an additional variable, myAV torque
Variable Type: Specific
Unit : N m
Tensor type: Scalar
3. Set in the rotor domain the additional variable
myTorque
Type: Algebraic
4. Set the transient statistic option
Output ? trn Stats ? New
Option : Arithmetic Average
Output variable List: myAV torque
5. After simulation you would have a new CFXPost variable (myAV Torque. Trnavg), at the required loaction (in this case at the Rotor blade)
