3.1.10.78. SimpleContact2D Element

This command constructs a two-dimensional contact element between a primary line segment (nodes i-j) and a secondary node using a Lagrange multiplier node. Use with -ndm 2.

element SimpleContact2D $eleTag $iNode $jNode $secondaryNode $lambdaNode $matTag $tolGap $tolForce

Argument	Type	Description
$eleTag	integer	unique element tag
$iNode $jNode	integer	nodes defining the primary contact segment
$secondaryNode	integer	secondary (slave) node
$lambdaNode	integer	Lagrange multiplier node
$matTag	integer	tag of a contact ND material
$tolGap	float	gap tolerance for contact detection
$tolForce	float	force tolerance for contact equilibrium

Note

Valid Element Recorder queries include forces and force.

Example

1. Tcl Code

element SimpleContact2D 1 1 2 10 11 1 1.0e-6 1.0e-6

2. Python Code

element('SimpleContact2D', 1, 1, 2, 10, 11, 1, 1.0e-6, 1.0e-6)
