contact property command

Syntax

contact property keyword ... <inheritance b > ...

Assign contact properties. All contacts with a contact model that recognizes the property are affected. Inheritance may also be modified with the optional inheritance keyword, followed by a boolean.

By default, only mechanical contacts are considered.

The list of built-in mechanical contact models is given in the “Built-in Contact Models” section. In the documentation for each contact model, a Properties table exists. These include: the linear, linear contact bond, linear parallel bond, hertz, hysteretic, smooth joint, flat joint, and fish property tables. Users may also implement custom contact models and properties (see “User-Defined Contact Models” for further information).

mechanical

Apply to mechanical contacts.

thermal

Apply to thermal contacts.
