Analysis of operator splitting for advection-diffusion-reaction problems from air pollution modelling
D. Lanser,Jan Verwer +1 more
TL;DR: In this paper, a general expression is derived for a three-term Strang splitting in the pure initial value case, for a class of advection-diffusion-reaction problems the splitting error is analyzed in greater detail.
Journal Article
Time integration of the shallow water equations in spherical geometry
D. Lanser,Joke Blom,Jan Verwer +2 more
TL;DR: In this article, a third-order, A-stable, Runge-Kutta-Rosenbrock method is proposed to solve the shallow water equations in spherical geometry.
Journal ArticleDOI
Time integration of the shallow water equations in spherical geometry
D. Lanser,Joke Blom,Jan Verwer +2 more
TL;DR: A third-order, A-stable, Runge–Kutta–Rosenbrock method is discussed and demonstrated to reduce the costs related to the linear algebra operations, this linearly implicit method is combined with approximate matrix factorization.
Journal ArticleDOI
Spatial discretization of the Shallow water equations in spherical geometry using Osher's scheme
D. Lanser,Joke Blom,Jan Verwer +2 more
TL;DR: In this paper, the use of Osher's finite-volume scheme for the spatial discretization of the shallow water equations on the rotating sphere has been studied and applied on the common (reduced) latitude-longitude grid and on a stereographic grid.
