Abstract: For the large dissipation problem of the multimaterial Global ALE method based on the Euler equation with integral form combined with the mass fraction equation, we use the high resolution anti-diffusive idea for interface based on the Euler equation with differential form to control the numerical diffusion at interface, and then we developed a multimaterial cell-centered ALE method based on the Euler equation with integral form combined with the mass fraction equation and volume fraction equation in plane coordinate to simulate the large deformation multimaterial interface with high resolution.
