Webcut cell mesh using the discontinuous Galerkin (DG) method in two dimensions with piecewise linear polynomials. The goal is to allow for explicit time stepping schemes, despite the presence of cut cells. Using a method of lines approach, we start with a standard upwind DG discretization for the background mesh and add penalty terms The cut-cell approach is used for dealing with material boundaries embedded within a structured (usually Cartesian) computational grid. Since it does not require any adjustment of the underlying logically rectangular mesh, it avoids the mesh-generation issues associated with other methods for dealing with complicated solid boundaries, such as ...
