Detailed Description

Restraint setting angular velocity of the rigid body. Developed from the linear axial angular spring restraint.

Adds a rotation along given axis to the body. Used for a combination of 6DOF bodies where one is driven by 6DOF and the other attached to it using specified rotation in the local reference frame.

Usage

Property	Description	Required	Default value

omega	Angular velocity (rad/s)	yes
relax	Relax moment with previous iter	yes
p	Propoptional corrector for PDI	yes
d	Differential corrector for PDI	yes
