Note: To run several complete rotations quickly, we will use a time step size such that the impeller rotates through a complete blade passage with every time step.
To determine the time step size, click the ... button on the Time Step Size line.
Click Number of Blades, and enter 4. Click the Calculate button. This sets the time step size to be 0.025 seconds.
Save Intervals_Results = 4.
Time Steps to run = 70.
