Detailed Description

Base class for coordinate mappings.

()

This class is the basic class for describing the mapping between the grid coordinates $(\xi, \theta', \phi')$ and the physical coordinates $(r, \theta, \phi)$ [cf. Bonazzola, Gourgoulhon & Marck, Phys. Rev. D 58, 104020 (1998)]. The class Map is an abstract one: it cannot be instanciated. Specific implementation of coordinate mappings will be performed by derived classes of Map.

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).

The mapping is defined with respect to some ``absolute'' reference frame, whose Cartesian coordinates are denoted by (X,Y,Z). The coordinates (X, Y, Z) of center of the mapping (i.e. the point r =0) are given by the data members (ori_x,ori_y,ori_z). The Cartesian coordinate relative to the mapping (i.e. defined from $(r, \theta, \phi)$ by the usual formul $x=r\sin\theta\cos\phi, \ldots$) are denoted by (x,y,z). The planes (x,y) and (X,Y) are supposed to coincide, so that the relative orientation of the mapping with respect to the absolute reference frame is described by only one angle (the data member rot_phi).
