Type string: "rigid contractile force"

Parameters

Name	Description	Default	Units
body_a	body_a	-842150451	[]
body_b	body_b	-842150451	[]
f0	f0	0	[]

Description

The rigid contractile force applies an actuator force between arbitrary points (not necessarily nodes) on two rigid bodies \(a\) and \(b\).

The f0 parameter represents the actuator force (positive for contraction). Optionally, it may be associated with a load curve.

Example:

<rigid_connector 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>
</rigid_connector>
