Detonation Shock Dynamics (DSD) can be used to model the effects that shock curvature, {kappa}, has oil detonation speed, D{sub n}({kappa}). At the edges of the explosive, D{sub n}({kappa}) is supplemented with boundary conditions. By direct numerical simulation (DNS). The authors study how the reaction zone interacts with the edge. DSD theory has been integrated with the level-set method of Osher and Sethian and the Los Alamos DNS code Mesa to create a powerful tool for simulating complex explosive containing systems.
