Detailed Description

Initialize particle related structures and functions.

PURPOSE: Initialize particle related structures and functions. Particle integrator is enrolled by calling integrate_particle_init(int type). In init_particle(Grid *pG, Domain *pD), all the particle related arrays are allocated, interpolation and stopping time calculation functions are enrolled, most global variables for particles are evaluated. Also contains functions for particle array reallocation and destruction.

CONTAINS PUBLIC FUNCTIONS:

• integrate_particle_init();
• init_particle();
• particle_destruct();
• particle_realloc();

Function Documentation

void grid_limit	(	Grid *	pG,
		Domain *	pD
	)

Calculate the left and right grid limit.

Input: pG: grid; Output: ilp,iup,jlp,jup,klp,kup: grid limit indices; x1lpar,x1upar,x2lpar,x2upar,x3lpar,x3upar: grid boundary coordinates

Initialization for particles.

Allocate memory for the gas velocity/sound speed array, feedback array. Note we enforce that each type has equal number of particles to ensure equal resolution.
