Preconditioners for the Onsager-Stefan-Maxwell equations for multicomponent diffusion

Kars Knook, Aaron Baier-Reinio, Patrick E. Farrell

The Onsager-Stefan-Maxwell (OSM) equations are an important model of mass transport in multicomponent flows with multiple chemical species. They describe the coupling of diffusive…

Shifted HSS solvers for the indefinite Helmholtz equation

Colin J Cotter, Kars Knook, Joshua Hope-Collins

We provide an iterative solution approach for the indefinite Helmholtz equation discretised using finite elements, based upon a Hermitian Skew-Hermitian Splitting (HSS) iteration a…

Quasi-optimal complexity hp-FEM for the Poisson Equation on a rectangle

Kars Knook, Sheehan Olver, Ioannis P. A. Papadopoulos

We show, in one dimension, that an hp-Finite Element Method (hp-FEM) discretisation can be solved in optimal complexity because the discretisation has a special sparsity struct…
