The relations are obtained in the following way:

  • Link the displacement of the two nodes (N1 and N2) according to the rigid body motion equations, except for the translation in the direction N1N2.
  • Impose a minimal overlap between the two nodes in the direction N1N2
Important: If the length of the beam is null, the direction given by the property is used.

Tightening elements generate a two-steps computation:

  • Submit a tightening force.
  • Impose a minimum overlap equal to the overlap obtained in the first step.
