Verify the Scenario Type is Known Rotational Speed
Click the Rotational Speed button.
Variation Method = Table
Rotational Speed Units = RPM; Time Units = second
Rotational Speed = 0; Time = 0
Rotational Speed = 600; Time = 0.75
Rotational Speed = 600; Time = 100
NoteThe values in the table are designed to ramp up the rotational speed of the impeller gradually to avoid an impulsive start. This technique often reduces analysis instability, and improves overall accuracy of the solution.
