Insert: 2-Point Link

Description

Inserts a 2-point link between two nodes.

A 2-point link implements a general constraint equation between two nodes. The equation has the form where , and are constants, and represent degrees of freedom in the nominated UCS, and and are the nodes.

Connectivity

The link is defined by clicking two points in the model window. Points may be nodes, grid points or vertices. A new node is automatically inserted when a grid point or vertex is clicked.

Dialog

Coordinate System (Node 1 / Node 2)

Coordinate system (UCS) in which the constrained degrees of freedom are defined. Each node can reference a different UCS.

Factors (Node 1 / Node 2)

Coefficients of the selected degree of freedom for each node in the constraint equation.

DoF (Node 1 / Node2)

Selected degree of freedom for each node in the constraint equation.

Constant

Constant that appears in the constraint equation.

Nonlinear Control Freedom Case

Freedom case used to scale the constant during a load step of a nonlinear analysis, based on the factor applied to the selected freedom case.

Link group

The group to which the inserted link is added. See Target group.
