Set up sequential transient events

To set up a series of sequential transient events:

1. Create the first event (see Create an event for steps).

2. Apply excitations (see Excitation loads for more information).

3. Calculate the modal response (see Solve for modal response for steps). The software saves the EEF file after generating the modal responses. This EEF file contains the information you will use as the initial conditions for the next event in the sequence.

4. Create the second event. On the New Event dialog box, under Initial Conditions, choose User Defined.

5. Click User Defined Initial Condition .

6. In the User Defined Initial Conditions dialog box, click From Existing EEF File.

7. In the Existing EEF File box, enter or browse to the folder where your EEF file is stored (the same folder where your model and simulation files are located). The mode information stored in the EEF file displays in the Initial Conditions list for your reference.

8. Click OK to close the User Defined Initial Conditions dialog box.

9. Create the next event.

You can repeat this process to extend the transient analysis over many events, provided the modal model (that is, modal shapes and natural frequencies) remains the same.
