1D mesh allows accurate testing of connectors (such as bolts) and similar rod-like or bar-like objects that can be modeled as a simple line for FEA purposes.
One dimensional elements currently supported include bar2s, bar3s, rigid links, rbe3s, plots, rigids, rods, springs, welds, gaps, and joints. The following list indicates the storage capabilities and purpose of each of the 1D elements.
