# CONN1

Connector ElementCONN1 lets you connect NLFE elements that have nonstructural discontinuity.

## Format

<CONN1
id       = "integer"
g1       = "integer"
g2       = "integer"
conn     = "string"
[graph    = "integer"]/>

## Attributes

id
Unique identification number.
g1
First grid identification number.
g2
Second grid identification number, $\text{g1}\ne \text{g2}$ .
conn
String containing at most 12 characters that describe the connection between the coordinates.4
graph
Post processing flag. Use this flag to control how this element is displayed in the animation H3D. Default for graph is 0. 6.

## Example

The example demonstrates the definition of a CONN1 element.

<CONN1 id="1000" g1="101" g2="17" conn="TTTFFFTTTFFF"/> 

$\begin{array}{l}{r}_{1}={r}_{2}\\ r{x}_{1}=r{x}_{2}\\ r{y}_{1}=r{y}_{2}\\ r{z}_{1}=r{z}_{2}\end{array}$
4. The letter 'T' in attribute conn indicates the particular kinematic relationship that will be imposed by MotionSolve at all times during the simulation. The attribute conn can have up to 12 'T' (True) or 'F' (False) characters. For example, if conn="TTTFFFFFFFFF", the first three conditions ( ${r}_{1}={r}_{2}$ ) will be imposed and the rest of the conditions (for example, $r{x}_{1}=r{x}_{2}$ , $r{y}_{1}=r{y}_{2}$ , and $r{z}_{1}=r{z}_{2}$ ) will not be imposed by MotionSolve.
