Definition

The rigid link option imposes the same velocity on all slave nodes for one or more directions. Directions are defined to a skew or a global frame, velocity is computed with momentum conservation. No global moment equilibrium is respected. A rigid link is equivalent to an infinite stiff spring type 8.

Note:A rigid link is a RADIOSS Engine input. A rigid link is alive only during the current restart run. For permanent rigid bodies, the input has to be repeated in each Engine input deck.
