GRAINS is a code for simulating granular mechanics-governed rubble pile asteroid systems, produced during the MSCA-PF of Fabio Ferrari, and expanded under the ERC Starting Grant TRACES.New simulations cannot be produced without also installing GRAINS (distributed separately), although the calculations performed herein might still be of scientific use/interest.
