#include <snapshot/body.h> #include <snapshot/barebody.h> Descriptionbody.h contains the definition of a standardized structure used to represent a point-mass particle, including several useful auxiliary fields. barebody.h defines a more minimal structure containing only mass and phase-space information. The details of the actual representation are hidden behind the following preprocessor macros, which completely define the structures from the point of view of an applications programmer. Body A typedef struct used to declare an instance of a body. Mass(b) Mass of body b, a real value. Phase(b) Phase-space coordinates of b, an array of two vectors (see vectmath.h(3NEMO)). Pos(b) Position coordinates of b, a vector. Vel(b) Velocity coordinates of b, a vector. Phi(b) Gravitational potential at position of b, a real value. Acc(b) Gravitational acceleration of b, a vector. Aux(b) Auxiliary real value for b. Key(b) Auxiliary integer value for b. See Alsoget_snap(3NEMO), put_snap(3NEMO), snapshot(5NEMO). AuthorJoshua E.
