Theory

The schematic is shown as follows.

TranslationConnector

The initial position of node \(k\) is not necessarily on the line defined by nodes \(i\) and \(j\).

The TranslationConnector will pull node \(k\) to the (closest point of) line defined by nodes \(i\) and \(j\).

The ratio \(c\) is computed according to the initial positions and remains constant during the analysis.
