3.11.2.10 Rigid Contractile Force
The rigid contractile force applies an actuator force between arbitrary points (not necessarily nodes) on two rigid bodies and .
In addition to the shared parameters above, it defines the following parameters.
| parameter | Description |
| f0 | The applied force (1) |
| insertion_a | Insertion point of the spring on body a |
| insertion_b | Insection point of the spring on body b |
Comments:
- The f0 parameter represents the actuator force (positive for contraction). Optionally, it may be associated with a load curve.
Example:
<constraint type="rigid contractile force"> <body_a>1</body_a> <body_b>2</body_b> <insertion_a>0,0,1</insertion_a> <insertion_b>0,0,3</insertion_b> <f0 lc="1">1</f0> </constraint>
