Use the Find Connectivity tool to check the connectivity between two or more components. Certain types of connections can be included or excluded while checking for connectivity.

The Find Connectivity is only available in the LS-DYNA and RADIOSS user profiles.

1.Open the Find Connectivity browser, from the menu bar, by clicking Tools > Find Connectivity.
2.Invoke the Find Connectivity controller by right-clicking in the browser and selecting Find Connectivity from the context menu.

3.In the Find Connectivity controller, enable the type(s) of connectivity to include in the check.

By default, all types of connectivity are enabled by except Connectors.

find_connectivity_checks

4.Using the Select Entities selector, select two or more components to check the connectivity between.

Connectivity check works on all the selected components regardless of its display state. Connectivity due to mass elements are completely excluded when checking connectivity.

5.Click Check. Results are displayed in the browser.

If two or more parts are connected, the number of connected parts are displayed in the browser. Expand the folders to see individual components. If the parts are free, the free part is displayed separately.
