Set up a Dynamic Event Simulation analysis

Overview video (7:35)

Workflow: Run a dynamic Event Simulation analysis

1. Click (Simulation workspace > Setup tab > Study panel > New Simulation Study) to open the New Study dialog.

2. In the New Study dialog, select Dynamic Event Simulation.

3. Click Settings in the top right corner of the Dynamic Event Simulation description, to open the Settings dialog.

4. In the General tab, type how long the event should take in Total Event Duration

   Note: The event duration is typically extremely short. The default value is 1 millisecond.

5. Type in the number of intermediate results you want in Number of Result Intervals.

   Note: The more results you enter, the more data you receive, but the larger the file size.

6. In the Mesh tab, check the mesh settings and adjust them as necessary.

7. Click Back, then Create Study to accept the input and create the new study.

8. Click (Simulation workspace > Setup panel > Rigid Bodies panel > Rigid Body) to specify the rigid bodies in your model.

9. Click (Simulation workspace > Setup panel > Materials panel > Study Materials) and select a nonlinear material from the Fusion Nonlinear Material Library.

10. Click (Simulation workspace > Setup tab > Constraints panel > Structural Constraint) to apply a structural constraints, as appropriate.

11. Click or (Simulation workspace > Setup tab > Constraints panel) to apply a prescribed displacement constraint, as appropriate.

    Note: In the Prescribed displacement constraints dialogs, make sure that the duration specified in your multiplier curves matches the Event Duration you specified in the study settings.

12. Click , or (Simulation workspace > Setup tab > Loads panel) to apply a transient or initial velocity load, as appropriate.

    Note: In the Transient Load dialog, if you activate the Time Dependent option, make sure that the duration specified in your Magnitude curves matches the Event Duration you specified in the study settings.

13. Click (Simulation workspace > Setup tab > Contacts panel > Global Contacts) to automatically generate contacts if multiple bodies are present.

    Note: In the Advanced Settings disable Allow Self Contact if you are sure that the bodies are unlikely to deform enough to contact themselves. This action shortens the solution time.

14. Adjust local mesh settings where appropriate: If you don't wish to adjust the default mesh settings, the mesh will be generated automatically at solve time. Refer to the Meshes section in the how-to branch of the Simulate help for more details.

15. Click (Simulation workspace > Setup tab > Solve panel > Pre-check) to confirm that the analysis set up is complete and the study is ready to solve.

    Note: The Pre-check may show an icon other than a green check, if there are items for you to investigate.

16. Click (Simulation workspace > Setup tab > Solve panel > Solve) to solve the analysis.

17. Review results: Refer to the View simulation results topic in this section for more details.

To change study settings

Study settings are adjusted in the Settings dialog:

1. Right-click the Event Simulation study in the browser and select Settings. The Settings can also be accessed from the ribbon toolbar (Manage panel > Settings).
2. Adjust any of the fields, as necessary.
3. Click OK.

Mesh Settings

The mesh settings can be adjusted in the Settings or Mesh Settings dialogs. For detailed information on the mesh settings available, refer to the Mesh Settings Dialog Box topic in the Reference branch of the Simulation Help.

Damping

Rayleigh damping represents the special case where the damping matrix is formed as a linear combination of the mass and stiffness matrices. To activate Rayleigh Damping, in the Settings dialog:

1. Switch to the Damping pane.
2. Activate the Rayleigh Damping check box.
3. Click OK.
