Efficient WENO-Based Prolongation Strategies for Divergence-Preserving Vector Fields
Autor: Dinshaw S. Balsara, Saurav Samantaray, Sethupathy Subramanian
Publikováno v: Communications on Applied Mathematics and Computation. 5:428-484
Adaptive mesh refinement (AMR) is the art of solving PDEs on a mesh hierarchy with increasing mesh refinement at each level of the hierarchy. Accurate treatment on AMR hierarchies requires accurate prolongation of the solution from a coarse mesh to a

Curl Constraint-Preserving Reconstruction and the Guidance it Gives for Mimetic Scheme Design
Autor: Michael Dumbser, Dinshaw S. Balsara, Roger Käppeli, Walter Boscheri
Publikováno v: Communications on Applied Mathematics and Computation, 5 (1)
Several important PDE systems, like magnetohydrodynamics and computational electrodynamics, are known to support involutions where the divergence of a vector field evolves in divergence-free or divergence constraint-preserving fashion. Recently, new

Modeling Magnetically Channeled Winds in 3D: I. Isothermal Simulations of a Magnetic O Supergiant
Autor: Sethupathy Subramanian, Dinshaw S Balsara, Asif ud-Doula, Marc Gagné
In this paper we present the first set of 3D magnetohydrodynamic (MHD) simulations performed with the riemann geomesh code. We study the dynamics of the magnetically channeled winds of magnetic massive stars in full three dimensions using a code that

Von Neumann Stability Analysis of DG-Like and PNPM-Like Schemes for PDEs with Globally Curl-Preserving Evolution of Vector Fields
Autor: Dinshaw S. Balsara, Roger Käppeli
Publikováno v: Communications on Applied Mathematics and Computation, 4 (3)
This paper examines a class of involution-constrained PDEs where some part of the PDE system evolves a vector field whose curl remains zero or grows in proportion to specified source terms. Such PDEs are referred to as curl-free or curl-preserving, r

Making a Synthesis of FDTD and DGTD Schemes for Computational Electromagnetics
Autor: Dinshaw S. Balsara, Jamesina J. Simpson
Publikováno v: IEEE Journal on Multiscale and Multiphysics Computational Techniques. 5:99-118
A novel class of discontinuous Galerkin time-domain (DGTD) schemes, invented by the first author, are presented that are capable of globally preserving the constraints that are inherent in Maxwell's equations. The methods share the same Yee-type mesh

Techniques, Tricks and Algorithms for Efficient GPU-Based Processing of Higher Order Hyperbolic PDEs
Autor: Sethupathy Subramanian, Dinshaw S. Balsara, Deepak Bhoriya, Harish Kumar
GPU computing is expected to play an integral part in all modern Exascale supercomputers. It is also expected that higher order Godunov schemes will make up about a significant fraction of the application mix on such supercomputers. It is, therefore,
