When using the soft soil interaction method, if the track link
geometry features different dimensions from the ones specified in the track properties, it is
required to use the update link geometry option. Figure 1. Update Link Geometry dialog
The default option is set to Auto Calculate, this option
considers the parameters specified in the track properties section. In case of different
track link geometry, the User Input option allows modify the
dimension of the track link. Figure 2. User input option in Update Link Geometry dialog
The contact points define how many points will represent that track link. The
maximum points allowed in the model is five. The figure below illustrates the track links
with 2, 3, 4, and 5 points. Figure 3. Contact points available in Update Link Geometry
The figure below shows an example of a CAD track link using 2 contact points
and the equivalent parameters in the Update Link Geometry dialog. Figure 4. Example of 2-point contact track link
