Functional Failure Injection Settings

Fault Injection settings are used when the user wants to disregard the failure diagram of an item and instead focus on simplified failure mode responses. Functional Failure injection is accessed from the Properties viewer when selecting an item.

To carry out Failure Injection:

1. Ensure the Properties viewer is open
2. Select an item from the project explorer, system or bond graph model
3. Select "Failure Injection" tab on the left side of Properties viewer
4. Check the "Enable Failure Injection" check-box
5. Select the "Activation" check-boxes to select or de-select failure mode responses
6. Save changes
