The DUNE grid module for moving interfaces

Dune-MMesh is an implementation of the DUNE [BBD+21] grid interface that is tailored for numerical applications with moving physical interfaces. The implementation based on CGAL [TCP20] triangulations supports two and three dimensional meshes and can export a predefined set of facets as a separate interface grid. In spatial dimension two, arbitrary movement of vertices is enhanced with a remeshing algorithm that implements non-hierarchical adaptation procedures. We present a collection of Examples based on the python bindings of the discretization module dune-fem [DNK+20].
