Analysis of the TNT decomposition reaction that occurs in the mixed crystal of TNT and RDX gives important knowledge for industrial application such as detonation synthesis of nanodiamonds. We have been tracking the chemical reaction process that occurs in the mixed crystal of TNT/RDX. For efficient evaluation, we proposed to use evolutionary algorithm (EA), which is used for material structure search and new material prediction under high pressure condition, for tracing the detonation reaction process. In this presentation, we show a method for rapid evaluation of mass transport peculiar to mixed crystals.
