Abstract
We develop an adaptive method for solving onedimensional systems of hyperbolic conservation laws that employs a high resolution Godunovtype scheme for the physical equations, in conjunction with a moving mesh PDE governing the motion of the spatial grid points. Many other moving mesh methods developed to solve hyperbolic problems use a fully implicit discretization for the coupled solutionmesh equations, and so suffer from a significant degree of numerical stiffness. We employ a semiimplicit approach that couples the moving mesh equation to an efficient, explicit solver for the physical PDE, with the resulting scheme behaving in practice as a twostep predictorcorrector method. In comparison with computations on a fixed, uniform mesh, our method exhibits more accurate resolution of discontinuities for a similar level of computational work.
