184.108.40.206 Rigid Spring
The rigid spring applies a linear spring that connects two rigid bodies and at arbitrary points (not necessarily nodes).
In addition to the shared parameters above, it defines the following parameters.
|k||spring constant (in units of force per length)|
|insertion_a||Insertion point of the spring on body a|
|insertion_b||Insection point of the spring on body b|
|free_length||The length of the unloaded spring (1)|
- If the free_length parameter is zero, then the initial length of the spring, as defined by the two insertion points, is taken as the free length.
<constraint type="rigid spring"> <body_a>1</body_a> <body_b>2</body_b> <insertion_a>0,0,1</insertion_a> <insertion_b>0,0,3</insertion_b> <k>1</k> </constraint>
