X Abstract

A Semi-Lagrangian Inherently Conserving and Efficient (SLICE) scheme is described for transport of passive scalars in Cartesian geometry. It is based on a Control-Volume (CV) approach and uses multiple sweeps of a one-dimensional O(x4) conservative remapping algorithm along pre-determined cascade directions. The scheme is applied to standard two-dimensional tests from the literature. Overall, it is found that in addition to conserving mass exactly, it is also competitive with standard non-conserving semi-Lagrangian schemes from the viewpoints of both computational efficiency and accuracy.

This is basically a type of cascading, conservative approach using piecewise cubics (aka, at least a 4-point stencil)

CiteULike organises scholarly (or academic) papers or literature and provides bibliographic (which means it makes bibliographies) for universities and higher education establishments. It helps undergraduates and postgraduates. People studying for PhDs or in postdoctoral (postdoc) positions. The service is similar in scope to EndNote or RefWorks or any other reference manager like BibTeX, but it is a social bookmarking service for scientists and humanities researchers.
