Examining the Imported Geometry

The imported CAD parts, which represent the different parts of the fuse and its holder, are contained in the Geometry > Parts manager node.

The various parts were previously imprinted on each other to provide pairs of matching faces on the surfaces that are in contact. STAR-CCM+ detects the matching faces on import, and creates part/part contact data that are used later to define interfaces between regions.

These contacting surfaces can be viewed successively as follows:

  1. Right-click the Geometry > Contacts node and select Browse Part/Part Contacts.
  2. In the Part/Part Contact Browser Options dialog, make sure that all the parts are selected and click OK.
    The Part/Part Contact Browser dialog opens in the edit window and a scene in the Graphics window.
  3. Select Wire from the Source Parts menu. Use the navigation buttons under the Target Parts menu to step through the Clip+ve, Clip-ve, and Silicium parts with which the wire is in contact.
  4. Click Close.
The surfaces and part curves of geometry parts are stored as individual entities on which operations can be performed if necessary. No further operations are required in this tutorial, but it is instructive to examine the surfaces for the electric potential.
  1. Open the Parts > Clip+ve > Surfaces and Parts > Clip-ve > Surfaces nodes. Multi-select the terminal+ and terminal- nodes.


    These surfaces are highlighted in the Graphics window.

  2. Use the mouse buttons to zoom in and position the part so that the view appears as shown.
  3. Click (Save-Restore-Select Views) in the Vis toolbar and select Store Current View.
