Abstract:

Objective The goal of this project is to challenge and expand the current understanding of how numerical methods And emerging computational architectures can be used to predict the dynamics of dry granular systems. At mesoscale, the research will seek high fidelity Direct Numerical Simulation DNS methodologies that increase the size of the granular systems tackled in a fully resolved, discrete, fashion by three orders of magnitude.
