A Local Discontinuous Galerkin Level Set Reinitialization with Subcell Stabilization on Unstructured Meshes
Ali Karakus, Noel Chalmers, Tim Warburton
In this paper we consider a level set reinitialization technique based on a high-order, local discontinuous Galerkin method on unstructured triangular meshes. A finite volume based…

Initial Guesses for Sequences of Linear Systems in a GPU-Accelerated Incompressible Flow Solver
Anthony P. Austin, Noel Chalmers, Tim Warburton
We consider several methods for generating initial guesses when iteratively solving sequences of linear systems, showing that they can be implemented efficiently in GPU-accelerated…
