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. |
