2D Basis Functions for Triangular and Rectangular Meshes,, the meshes will be presented as structured. For research in new numerical methods, structured test models have the advantage of being easy to create. Unstructured programming is conveniently done by using a neighborhood management system, which is present in the MPAS, COSMO, and Fluidity models.

Finite Difference Schemes on Sparse and Full Grids,ilities is too large. So just examples are presented to show how the schemes work. In particular, most examples are 2D. While the complexity of computer programs normally increases substantially when going to 3D, it is often obvious how to proceed from 2D to 3D.

A well-known example is the spectral element (SE) method, but there exist a large number of alternatives, named o.o. or the third-degree method. o.o. approximates the fields in order . and the fluxes in order ..

Finite Difference Schemes on Sparse and Full Grids,ty to make models more efficient for the same resolution. This section aims at transferring some of the 1D schemes defined in Chapter “Local-Galerkin Schemes in 1D” to two dimensions. There is no way the most general L-Galerkin scheme or a class of such schemes can be presented. The number of possib

However, the tools and the example provided in Chapters “Finite Difference Schemes on Sparse and Full Grids” and “Full and Sparse Hexagonal Grids in the Plane” allow to create L-Galerkin sparse grids on the sphere. Further L-Galerkin methods will be present
