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.
