Multigrid preconditioners for the hybridized Discontinuous Galerkin discretisation of the shallow water equations

Jack D. Betteridge, Thomas H. Gibson, Ivan G. Graham +1

Numerical climate- and weather-prediction requires the fast solution of the equations of fluid dynamics. Discontinuous Galerkin (DG) discretisations have several advantageous prope…

Domain decomposition preconditioners for high-order discretisations of the heterogeneous Helmholtz equation

Shihua Gong, Ivan G. Graham, Euan A. Spence

We consider one-level additive Schwarz domain decomposition preconditioners for the Helmholtz equation with variable coefficients (modelling wave propagation in heterogeneous media…
