Notes:
We present an innovative method of multi-physics application involving energeticmaterials. Energetic materials are related to reacting flows in extreme environments such as firesand explosions. They typically involve high pressure, high temperature, strong non-linear shockwaves, and high strain rate deformation of metals. We use an Eulerian methodology to addressthese problems. Our approach is naturally free from large deformation of materials that makes itsuitable for high strain-rate multi-material interaction problems. Furthermore we eliminate thepossible interface smearing by using the level sets. We have devised a new level set based trackingframework that can elegantly handle large gradients typically found in reacting gases and metals.We show several work-in-progress applications of our algorithm including the Taylor impact test,explosive venting and additional confined explosion problems of modern interest
