For this profile only, the following Import Choice for Units dialog appears if your unit system selection is questionable.
Clicking the More Info ... button issues the following message about units:
"When starting HyperCrash, you must specify the correct units for the session. If the units are incorrect, errors could result in tasks, such as, error-check, time-step calculation, or part-replacement, or affect access to the material database. Units also play a role when importing a deck. If the imported file does not have the same units as the current session, HyperCrash issues a warning and prompts you to select from the following: cancel the import event, convert the imported file units to match the units in the session, or ignore the warning and import the file.
From the Units Manager, which is accessible from the Model pull-down menu, you can review the units in your model, and then convert them from one system to another."
Select an interface style for your session:
• | New |
• | Standard |
• | Classic |
If Always show at start-up is selected, the user profile opens with the option to change the settings. If Always show at start-up is not selected, HyperCrash opens using previous settings.
After you invoke HyperCrash, you can change this feature in the Options menu.
