A Browse for Folder dialog appears.

User Profile

•Open the User profile pull-down and select from a user profile for RADIOSS, LsDyna or PAM2G.

The sub-menus in each of these profiles may differ slightly.

The LS-DYNA profile differs most noticeably from the other profiles.  A menu option, LS-DYNA Tools, is found only in the LS-DYNA profile, and some differences exist in the sub-menus of Connections, Mesh Editing, Model and LoadCase.  In this guide, options that are applicable only to the LS-DYNA profile are marked accordingly. See also: LS-DYNA and RADIOSS Profiles.

 

Unit System

•From the pull down, select a Unit System for your session.

The following table describes the environment for each of the unit systems. Note that once you choose a unit system for a model, only the databases within that particular unit system are available to you for that model.

RADIOSS User Profile

For this profile only, the following Import Choice for Units dialog appears if your unit system selection is questionable.

units_more_info_dialog

 

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."

 

User Interface Style

Select an interface style for your session:

•New
•Standard
•Classic

 

Start-Up Setting

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.
