Hybridised multigrid preconditioners for a compatible finite element dynamical core
Jack D. Betteridge, Colin J. Cotter, Thomas H. Gibson +3
Compatible finite element discretisations for the atmospheric equations of motion have recently attracted considerable interest. Semi-implicit timestepping methods require the repe…

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…
