摘要: An invariant domain preserving arbitrary Lagrangian-Eulerian method for solving nonlinear hyperbolic systems is developed. The numerical scheme is explicit in time and the approximation in space is done with continuous finite elements. The method is made invariant domain preserving for the Euler equations using convex limiting and is tested on various benchmarks.
