A Weighted State Redistribution Algorithm for Embedded Boundary Grids
Andrew Giuliani, Ann S. Almgren, John B. Bell +3
State redistribution is an algorithm that stabilizes cut cells for embedded boundary grid methods. This work extends the earlier algorithm in several important ways. First, state r…

A coupled discontinuous Galerkin-Finite Volume framework for solving gas dynamics over embedded geometries
Vincenzo Gulizzi, Ann S. Almgren, John B. Bell
We present a computational framework for solving the equations of inviscid gas dynamics using structured grids with embedded geometries. The novelty of the proposed approach is the…
