Syntax
- contact cmat modify i keyword ... <range>
-
Modify an existing entry in the CMAT. Assigns the information specified by the keywords to slot i of the CMAT.
By default, only mechanical contacts are considered.
- mechanical
Apply to mechanical contacts.
- method s <sa a> ...
The contact model method s, along with its specific list of pairs of argument names and values (sa, a) (if applicable), is registered with this cmat entry and will be invoked at contact creation.
- model keyword
Specify the 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.
- arrlinear
Specify the Adhesive Rolling Resistance Linear Model contact model.
- bilinear
Specify the Bilinear Contact Model contact model.

Specify the Burger’s Model contact model.
- fish
Specify the FISH Model contact model.
- flatjoint
Specify the Flat-Joint Model contact model.
- hertz
Specify the Hertz Model contact model.
- hysteretic
Specify the Hysteretic Model contact model.
- linear
Specify the Linear Model contact model.
- linearcbond
Specify the Linear Contact Bond Model contact model.
- lineardipole (3D ONLY)
Specify the Linear Dipole Model contact model.
- linearpbond
Specify the Linear Parallel Bond Model contact model.
- null
Specify the Null Model contact model.
- rrlinear
Specify the Rolling Resistance Linear Model contact model.
- smoothjoint
Specify the Smooth-Joint Model contact model.
- softbond
