contact cmat default command

Syntax

contact cmat <sprocess> default <type stype > keyword ...

Primary keywords:

inheritance    method    model    property    type

Set the default slot(s) of the CMAT. Attempts to assign the following information to the default slot(s) of the CMAT. If the optional keyword type is issued, then it must be followed by a valid contact type name, and the corresponding default slot of the CMAT will be modified. If no type is specified, then the command will attempt to modify all the default slots.

By default, only mechanical contacts are considered. If sprocess is specified, then it must correspond to a process name and contacts within this process are considered.

inheritance sprop b ...

The inheritance flag for the contact model property sprop is set to b. The property sprop must support inheritance.

method sm <sa a>

The contact model method sm, along with its specific list of pairs of argument names and values (sa, a) (if applicable), is registered with the selected default slot(s) and will be invoked at contact creation.

The list of available methods is contact model specific. Visit the documentation of the desired contact model for details.

model keyword

Specify the default model. The default slot(s) will not be modified if the corresponding contact type(s) cannot use the specified contact model.

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) and register them in the CMAT.
