Change the contact activate flag. The flag is set according to the value of the boolean bval. If set to “on,” the activate flag is set so that the contact is always in an active state until the contact is deleted automatically by the contact detection system. In addition, the inhibit flag is set to false. If set to “off,” the contact activity is determined by the contact model.

By default, only mechanical contacts are considered.


The activate flag is off by default. The activity state is set to true regardless of the contact resolution strategy for ball-facet or pebble-facet contacts.


Apply to mechanical contacts.


Apply to thermal contacts.
