Refining the Eulerian flow model
Magnus Svärd
We revisit the molecular arguments underpinning the Eulerian model for compressible and diffusive flows, and conclude that a heat diffusive term appears to be missing in the origin…

A novel energy-bounded Boussinesq model and a well balanced and stable numerical discretisation
Magnus Svärd, Henrik Kalisch
In this work, a novel Boussinesq system is put forward. The system is naturally nonlinearly entropy/energy-stable, and is designed for problems with sharply varying bathymetric fea…

A Stable Implementation of a Well-posed 2-D Curvilinear Shallow Water Equations with No-Penetration Wall and Far-Field Boundary conditions
Reindorf N. Borkor, Magnus Svard, Adu Sakyi +1
This paper presents a more stable implementation and a highly accurate numerical tool for predicting flooding in urban areas. We started with the (linearised) well-posedness analys…
