A New Re-redistribution Scheme for Weighted State Redistribution with Adaptive Mesh Refinement
Isabel Barrio Sanchez, Ann S. Almgren, John B. Bell +2
State redistribution (SRD) is a recently developed technique for stabilizing cut cells that result from finite-volume embedded boundary methods. SRD has been successfully applied t…
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…
A Hybrid Adaptive Low-Mach-Number/Compressible Method: Euler Equations
Emmanuel Motheau, Max Duarte, Ann Almgren +1
Flows in which the primary features of interest do not rely on high-frequency acoustic effects, but in which long-wavelength acoustics play a nontrivial role, present a computation…
