Display General Link Table
Boundary Group Name
Select a boundary group to which the entered boundary condition will be assigned. Select Default if the Group selection is unnecessary. To create new or modify predefined Boundary Groups Click to the right to prompt the "Define Boundary Group" dialog box.
Options
Add : Select to add new or replace previously entered general link elements individually linking two nodes.
Delete : Select to delete previously entered general link elements individually linking two nodes.
General Link Data
General Link Property : Assign the property of general link element.
Name : Assign a name of General Link Property.
Click to the right to prompt the General Link Property dialog box to create or modify General Link Property.
General Link Type : It displays the Type of the specified General Link Property.
Inelastic Hinge Property
Name : The Name of selected Inelastic Hinge Property is displayed.
Reference Coordinate System
Define a coordinate system in which the placement directions of general link elements can be defined in 3-D space.
Element : Placement direction is determined on the basis of element coordinate system.
Input Method
Beta Angle : Enter a Beta Angle for the general link element (select 0, 90, 180).
Ref. Point : Enter a reference point in 3-D space.
Ref. Vector : Enter a directional vector in 3-D space.
Global : Placement direction is determined on the basis of global coordinate system.
Input Method
Angle : Direction is determined by orientation angles in each direction in 3-D space (select 0, 45, 90, 180).
3Points : Direction is determined by 3 points in 3-D space.
Vector : Direction is determined by 2 vectors (V1, V2) in 3-D space.
2 Nodes
Enter the numbers of the 2 nodes for which you want to input the general link element. You can use the mouse editor function to click on the two points, and the general link element will be inputted.
Copy Nonlinear Link
Input multiple general link elements simultaneously by duplicating the specified conditions in the General Link Data.
Node Inc.
Generate multiple general link elements simultaneously using the increment of node numbers.
Number of Times : Number of duplications.
Node Increment : Increment of node numbers.
Distance
Generate multiple general link elements simultaneously using the distance between nodes.
Axis : Specify the axis direction for duplication.
Distances : Input the distances and the number of duplications.
