Thetis coastal ocean model: discontinuous Galerkin discretization for the three-dimensional hydrostatic equations
Tuomas Kärnä, Stephan C. Kramer, Lawrence Mitchell +3
Unstructured grid ocean models are advantageous for simulating the coastal ocean and river-estuary-plume systems. However, unstructured grid models tend to be diffusive and/or comp…
Solver composition across the PDE/linear algebra barrier
Robert C. Kirby, Lawrence Mitchell
The efficient solution of discretisations of coupled systems of partial differential equations (PDEs) is at the core of much of numerical simulation. Significant effort has been ex…
TSFC: a structure-preserving form compiler
Miklós Homolya, Lawrence Mitchell, Fabio Luporini +1
A form compiler takes a high-level description of the weak form of partial differential equations and produces low-level code that carries out the finite element assembly. In this…
