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.
