Tractor-semitrailer web site help: Model/Contact

The Contact unit located in the drop line menu under the horizontal menu's Model tab offers data briefs from the CONTACT LS-DYNA keyword. Data queries are conducted on the selected model. Current model selection is indicated in the page title with the name of the FEM model source file name. Model selection can be made through the Model's Selection tab.

The contacts are conveniently grouped into smaller units according to their type. These units can be easily reached from the vertical navigation menu located at the left-hand side of the page. Current unit selection is highlighted in separate color.

Essential information about the contact interfaces used in the selected model is displayed in tabular format with each contact filling one data row. The data is appropriately linked to related model content.

Contact specifics can be reached by following the contact identification number link, or by selecting the checkbox adjacent to the contact identification number and then clicking on the Submit Query button located below the table(s). The latter approach is convenient for simultaneous selection of several contacts.

In contact specifics the essential data for the chosen contact(s) is accompanied with access to:

• Excerpt from the FEM model source file (Input Lines),
• Numerous images (standalone and in setting) of all parts featuring the chosen contact,
• Interactive 3D View of all parts featuring the chosen contact, and
• LS-DYNA's User's Manual displaying the chosen keyword entry.

Excerpt from the FEM model source file containing the chosen contact entry is accessible through the Input Lines link. A popup window shows the chosen contact entry conveniently numbered such that numbers correspond to the FEM model source file lines.

Numerous images of the parts featuring the chosen contact can be viewed through the Images link. A popup window shows images of the parts alone, and of the parts setting in the model taken from different viewing angles.

Images can be navigated by clicking inside the image on its left-hand and right-hand side, by clicking on the Previous and Next links that appear on mouse over the image event, by pressing the P and L letters on the keyboard, or by pressing the left and right keyboard arrows.
The image window can be dismissed by clicking anywhere outside the image area, by clicking the Close link, or by pressing the C letter on the keyboard.
