Cactus Code Thorn CartGrid3D Author(s) : Gabrielle Allen Gerd Lanfermann Joan Masso Maintainer(s): Cactus team Licence : LGPL

1. Purpose

This thorn sets up a Cartesian grid, for a given domain. It also provides a method for registering symmetries of Grid Functions across the grid axes, and a call for applying symmetry boundary conditions.

CartGrid3d also registers a coordinate system spher3d, under the old API, but this is deprecated. Spherical coordinate systems will be provided by another thorn in the future.

2. Additional information

This thorn currently only works in 3D, in that it creates 3D grid functions. It registers Cartesian coordinate systems of 1, 2, and 3 dimensions.
