Kelvin–Helmholtz instability simulation with adaptive mesh refinement

Simulation of a 2D Kelvin–Helmholtz instability with a discontinuous Galerkin spectral element method on a hierarchical Cartesian mesh with adaptive mesh refinement (AMR). The polynomial degree is N = 3 and the mesh uses four refinement levels from 4 to 7. Author(s): Gregor Gassner ()
