This option is used to specify the self-contact surfaces and surface pairings that should be considered by the general contact algorithm. It can be used once in conjunction each *CONTACT option.
Product: ABAQUS/Explicit
Type: Model or history data
Level: Model Step
Include this parameter to specify self-contact for a default unnamed, all-inclusive, element-based surface (defined automatically by ABAQUS/Explicit). This is the simplest way to define the contact domain. The option should have no data lines when this parameter is used; any data lines specified will be ignored.
If this parameter is omitted, the contact surfaces must be specified on the data lines.
First line:
The name of the first surface. If the first surface name is omitted, the default all-inclusive, element-based surface defined by ABAQUS/Explicit is assumed.
The name of the second surface. If the second surface name is omitted or is the same as the first surface name, ABAQUS/Explicit assumes that self-contact is defined. Self-contact means contact of a surface with itself, without consideration of whether a surface contains disconnected regions. If different names are specified for the first and second surfaces, self-contact is not considered except in any overlap between the two surfaces.
Repeat this data line as often as necessary.
