When trying to apply a moment generated by damping at a joint using a bushing force, should I specify a damping ratio or an angular damping coefficient. If it is a damping coefficient, should the units be in radians, degrees or cycles?

Thank you,
Heather

Hi Heather,

Thanks for reporting the issue. We've updated the documentation as follows to help resolve the ambiguity:

rotational_stiffness: Stiffness parameters resisting relative rotation (Nm/rad).
translational_stiffness: Stiffness parameters resisting relative translation (N/m). rotational_damping: Damping parameters resisting relative angular velocity. (Nm/(rad/s)).
translational_damping: Damping parameters resisting relative translational velocity. (N/(m/s)".

This will appear in the documentation of the next release.

Best regards,
