Assign contact models. The selected contact model applies to contacts in the specified range. If no range is specified, then all contacts in the model are affected. The contact model can be a built-in contact model, or a plug-in contact model (registered with the
program loadcommand).By default, mechanical contacts are considered. One can use the mechanical or thermal to refer to mechanical or thermal contacts.
The list of built-in mechanical contact models is given in the “Built-in Contact Models” section. Users may also implement custom contact models (see “User-Defined Contact Models” for further information).
