rigid_rotation_vector¶

Module: solid

Category: bc

Type string: "rigid_rotation_vector"

Parameters¶

Name	Description	Default	Units
`rb`	Rigid material	-1	[]
`vx`	vx	0	[r]
`vy`	vy	0	[r]
`vz`	vz	0	[r]

Description¶

The rigid_rotation_vector constraint allows the user to prescribe the rotation of a rigid body using a rotation vector. In essence, this combines the effect of using three separate rigid rotation constraints, one for each component of the rotation vector, and thus might be a more convenient choice if the rotation of the rigid body is fully prescribed.

The rb parameter is the name attribute assigned to the corresponding rigid body material as defined in the Material section.

The following example prescribes a rotation around the z-axis using a load controller.

<rigid_bc type="rigid_rotation_vector">
  <rb>rigid</rb>
  <vx>0</vx>
  <vy>0</vy>
  <vz lc="1">3.14</vz>
</rigid_bc>
