Von Neumann Stability Analysis of DG-like and PNPM-like Schemes for PDEs that have Globally Curl-Preserving Evolution of Vector Fields
Dinshaw S. Balsara, Roger Käppeli
This paper examines a class of 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…

Curl constraint-preserving reconstruction and the guidance it gives for mimetic scheme design
Dinshaw S. Balsara, Roger Käppeli, Walter Boscheri +1
Several important PDE systems, like magnetohydrodynamics and computational electrodynamics, are known to support involutions where the divergence of a vector field evolves in diver…
