We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Damping is a very complex topic and more information is needed to help you. In general, I usually use either DAMPING_PART_STIFFNESS and DAMPING_PART_MASS (Rayleigh Damping) or I use DAMPING_FREQUENCY_RANGE_DEFORM. The frequency damping provides constant (ish) damping between a range of specified frequencies. It only works well for low damping and you need to read the manual (and notes) carefully for this card.
