The Rotating Region Results file contains the time history of Rotating Region simulations. This file lists the hydraulic torque, rotating speed, and hydraulic force components for each rotating object.
Hydraulic Torque is the torque the blades must overcome to push through the fluid. This is different from torque imparted from a motor, which includes hydraulic torque plus bearing friction and shaft losses.
Hydraulic Forces are the forces imparted by the fluid on the impeller.
This data is also written to an external “.csv” file. The file name is the scenario name with the word torque appended to it. For example, the torque file from Scenario 1 is named: Scenario 1_torque.csv. This file is located in the scenario sub-folder of the design study directory structure.
