A comparative study of explicit differential operators on arbitrary grids

Kaser, Martin; Igel, Heiner; Sambridge, Malcolm; Braun, Jean


We compare explicit differential operators for unstructured grids and their accuracy with the aim of solving time-dependent partial differential equations in geophysical applications. As many problems suggest the use of staggered grids we investigate different schemes for the calculation of space derivatives on two separate grids. The differential operators are explicit and local in the sense that they use only information of the function in their nearest neighborhood, so that no matrix...[Show more]
