Dynamic simulations can benefit a lot from an appropriate damping approach. For example, the stability is improved and a larger time step can be chosen. Furthermore, badly shaped meshes, e. g. containing sharp angles or slivers, can be handled if a proper damping approach is used. However, it must be ensured that the damping forces do not change the global movement of the object, i. e. they have to preserve linear and angular momentum. In this paper, we present a novel damping approach that is based on iterative spring damping to further improve the stability. We show that the resulting forces can be computed directly without actually performing the iterations. The approach does not require any connectivity information about the object and therefore, it can be used for arbitrary object representations. Further, it is independent of the integration scheme and the deformation model. The approach provides a simple parameter setting and guarantees that the damping forces do not overshoot. Finally, we illustrate that our approach allows for larger time steps compared to existing damping methods.
