Reply To: Damping in lsdyna

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.
