cmat add
command
Syntax
- contact cmat add <i > keyword ... range
Primary keywords:
inheritance mechanical method model property proximity thermal
Adds a new entry to the CMAT. If i is not specified or if i is greater than the total number of entries minus one, then the new entry is added to the end of the CMAT; otherwise, the new entry is inserted at slot i (i>0) while incrementing subsequent entry indices as necessary. The
range
token is mandatory and must be specified last.By default, only mechanical contacts are considered.
The information in the entry is specified with the following keywords.
- mechanical
Apply to mechanical contacts.
- method sm <sa a> ...
The contact model method sm, along with its specific list of argument names and values, 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.
- burger
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
Specify the Soft-Bond Model contact model.
- springnetwork
Specify the Spring Network Model contact model.
- subspringnetwork
Specify the Subspring Network Model contact model.
- property s a<inheritance b > ...
The contact model property named s is set to a. If the inheritance keyword is specified, the inheritance for this property is set to b.
- thermal
Apply to thermal contacts.
