Define stationary nodes for CBEAR elements

  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 Bearing End Objects (ROTORB) group, next to Select Object, click Bearing End Objects (ROTORB) . In the graphics window, select the nodes that represent the stationary portion of the bearing supports for rotor 1.

  4. In the Region dialog box, click OK.

  5. Repeat steps 2 through 4 for other rotors that have bearing supports.

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