Location: From the Menu Bar, select Mesh Editing > HyperMesh.

The HyperMesh option lets you make extensive modifications to models during a HyperCrash session. This option opens a HyperMesh window in which you can modify your model, save your changes, and then resume your HyperCrash session.  Any changes you make to the HyperMesh source model are automatically updated in the HyperCrash session. To learn more about how to use HyperCrash, see the HyperMesh User's Guide.
