Continuum representation of granular material used to simulate mobility of VIPER rover replica

SBEL students Wei Hu and Jason Zhang collaborated on a simulation of a VIPER-replica rover operating on granular material. The highlight here is that the terrain was actually represented as a continuum material. This trick enabled the simulation to complete faster when compared to the case in which the terrain was considered to be made up of a large collection of grains of sand. It remains to also compare how accurate the results obtained with the faster simulation are. This is work in progress. Simulation of the rover is here. This work is related to the NASA project in which SBEL is producing simulation tools for the VIPER rover.
