Contact Pair Feature
A Contact Pair Feature () node is almost identical to the Pair Feature node. The difference is only visible for the feature instance in the Model Builder. A pair feature of the contact pair type can only select contact pairs. See Pair Feature for more information.
Using this feature also forces the Include geometric nonlinearity switch to be selected in study steps, which introduces extra license requirements.
To add a Contact Pair Feature:
•
On the Physics Interface toolbar, select it from the More Features menu.
•
Under Building Blocks, right-click Features and add it from the context menu.
•
Right-click the Physics Interface or Multiphysics Interface nodes to add this from the Features submenu.
