Mapping grid -> physical space (spherical coordinates)

These classes implement the mapping between the grid coordinates $(\xi, \theta', \phi')$ (described by the Mg3d class) and the physical coordinates $(r, \theta, \phi)$ [cf. More...

Detailed Description

These classes implement the mapping between the grid coordinates $(\xi, \theta', \phi')$ (described by the Mg3d class) and the physical coordinates $(r, \theta, \phi)$ [cf.

Bonazzola, Gourgoulhon & Marck, Phys. Rev. D 58 , 104020 (1998)].

The class Map and its derived classes determine the methods for partial derivatives with respect to the physical coordinates, as well as resolution of basic partial differential equations (e.g. Poisson equations).
