Maneuver load analysis with gyroscopic forces workflow

Step Detailed steps
1. Create the FEM and Simulation files for a SOL 101 Linear Statics solution.
2. Create the FE model. As a best practice, create a distinct mesh for each rotor.
3. Create coincident nodes at each bearing support location.
4. Create bearing supports. As a best practice, use CBEAR elements to model bearing supports. Define bearing supports between coincident nodes with CBEAR elements
5. Assign physical properties to the CBEAR elements. Assign physical properties to CBEAR elements
6. Define each rotor in the model. Define rotors
7. Map CBEAR elements to the appropriate rotor. Map CBEAR elements to rotors
8. Define stationary nodes for CBEAR elements. Define stationary nodes for CBEAR elements
9. Define system-wide rotor dynamic solution options. Define system-wide rotor dynamics solution options
10. Define rotor-specific rotor dynamic solution options. Define rotor-specific rotor dynamics solution options
11. Define rigid-body linear acceleration for the model. Static acceleration load
12. Define rigid-body angular velocity and angular acceleration for the model. Define a rotation load
13. Define other boundary conditions for the model.
14. Solve the model.
15. Post-process the results.
