A snapshot of one of our simulations as viewed in the open-GL viewer of rebound. We only show the tidally perturbed body, as the perturbing one is distant from it. The rendered spheres are shown to illustrate the random distribution of node point masses, not imply that the body behaves as a rubble pile (e.g. Richardson et al. 2009; Sánchez & Scheeres 2011). Nodes are connected with a network of damped elastic springs.
