Define rotors

1. Choose Home tab→Loads and Conditions group→Simulation Object Type list→Rotor Dynamics Definition .

2. In the Rotor Dynamics Definition dialog box, next to Rotor 1, click Create Region .

3. In the Region dialog box, in the Rotor Objects (ROTORG) group, next to Select Object, click Rotor Objects (ROTORG) . In the graphics window, select the nodes in the mesh of rotor 1.

4. In the Region dialog box, click OK.

5. Repeat steps 2 through 4 to define other rotors.

6. In the Rotor Dynamics Definition dialog box, click OK.
