DOI: 10.1002/qj.3108
Abstract: In this paper we outline a simple method to achieve mass conservation with Semi-Lagrangian based Limited Area Models (SL-LAM). Imposing mass conservation with LAMs requires knowledge of advective fluxes across their lateral boundaries. Estimation of… read more here.

DOI: 10.1103/physreve.101.053306
Abstract: This work thoroughly investigates a semi-Lagrangian lattice Boltzmann (SLLBM) solver for compressible flows. In contrast to other LBM for compressible flows, the vertices are organized in cells, and interpolation polynomials up to fourth order are… read more here.
