Kelvin–Helmholtz instability including mesh
2d simulation of a Kelvin-Helmholz instability. The Voronoi cells are shown explicitly in this move to illustrate the concept of a moving-mesh hydrodynamics simulation.
Higher resolution 2d simulation of a Kelvin-Helmholz instability.
Another Kelvin-Helmholz instability.
High resolution 2d simulation of a Rayleigh–Taylor instability.
Mesh movement of a differentially rotating disk simulation. The cell size depends on radius with increasing the resolution closer to the center.
Mesh movement in a Gresho-vortex problem, in which the inner part of the rotating disk shows solid-body rotation and the outer part differential rotation. Some cells are marked to better follow their movement.
2d simulation of a Sedov-Taylor test
