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 mixed finite element dynamical core of the LFRic atmospheric model
Christopher Maynard, Thomas Melvin, Eike Hermann Müller
Due to the wide separation of time scales in geophysical fluid dynamics, semi-implicit time integrators are commonly used in operational atmospheric forecast models. They guarantee…
