Abstract: During the arbitrary LagrangianEulerian (ALE) simulation, once the mesh moving, the variables related to the deformation history must be transferred from the old mesh to the new mesh so as to continue the next computational step. According to the theory of water wave transportation in hydrodynamics, the remapping procedure can be assumed as an advection problem. In this study, a remapping algorithm based on the combination of explicit second order RungeKutta discontinuous Galerkin method and limiter was used, which can eliminate the dispersion and local oscillation of the remapping result, and further improve the calculation accuracy of ALE simulation.
