Define rotor-specific rotor dynamics solution options

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 Parameters group, specify the rotor-specific solution options.For details on each of the solution options listed on the Region dialog box, see the ROTORD bulk entry in the Simcenter Nastran Quick Reference Guide.

4. In the Region dialog box, click OK.

5. Repeat steps 2 through 4 for the other rotors.

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