N2 - We propose a robust and high performance numerical scheme for complex fluid solid interactions, with arbitrary number of phases and various chemical reactions, to simulate the complex multiphase flow and the large deformation of elastoplastic solids under extreme loads produced by intensive detonations. The multiphysics system is modeled by a multi-component model solved using a generalized Godunov method, and a classical material point method in a combination of Lagrangian particles and nonlinear constitutive laws. The mass, momentum and energy transformations between different phases, due to the reduced and detailed chemical reactions, are solved by an implicit scheme. With the aid of high performance parallel computation and adaptive mesh refinement method, several large scale detonation wave and high speed impact problems are simulated in a reasonable time period, which can validate our numerical schemes and lead us to more practical engineering applications.
