Function Documentation

struct part* cell_add	(	struct cell *	c,
		struct part *	p,
		struct part **	partlist
	)		[read]

Add a particle to a cell.

Parameters:

c	The cell to which the particle should be added.
p	The #particle to add to the cell

Returns:

A pointer to the particle data in the cell.

This routine assumes the particle position has already been adjusted to the cell c.

struct part* cell_add_incomming	(	struct cell *	c,
		struct part *	p
	)		[read]

Add a particle to the incomming array of a cell.

Parameters:

c	The cell to which the particle should be added.
p	The #particle to add to the cell

Returns:

A pointer to the particle data in the incomming array of the cell.

This routine assumes the particle position has already been adjusted to the cell c.

int cell_add_incomming_multiple	(	struct cell *	c,
		struct part *	p,
		int	count
	)

Add one or more particles to the incomming array of a cell.

Parameters:

c	The cell to which the particle should be added.
p	The #particle to add to the cell

Returns:

The number of incomming parts or < 0 on error (see cell_err).

This routine assumes the particle position have already been adjusted to the cell c.

int cell_flush	(	struct cell *	c,
		struct part **	partlist,
		struct cell **	celllist
	)

Flush all the parts from a cell.

Parameters:

c	The cell to flush.
partlist	A pointer to the partlist to set the part indices.
celllist	A pointer to the celllist to set the part indices.

Returns:

cell_err_ok or < 0 on error (see cell_err).

int cell_init	(	struct cell *	c,
		int *	loc,
		double *	origin,
		double *	dim
	)

Initialize the given cell.

Parameters:

c	The cell to initialize.
loc	Array containing the location of this cell in the space.
origin	The origin of the cell in global coordinates
dim	The cell dimensions.

Returns:

cell_err_ok or < 0 on error (see cell_err).

int cell_load	(	struct cell *	c,
		struct part *	parts,
		int	nr_parts,
		struct part **	partlist,
		struct cell **	celllist
	)

Load a block of particles to the cell.

Parameters:

c	The cell.
parts	Pointer to a block of part.
nr_parts	The number of parts to load.
partlist	A pointer to the partlist to set the part indices.
celllist	A pointer to the celllist to set the part indices.

Returns:

cell_err_ok or < 0 on error (see cell_err).

int cell_welcome	(	struct cell *	c,
		struct part **	partlist
	)

Move particles from the incomming buffer to the cell.

Parameters:

c	The cell.
partlist	A pointer to the partlist to set the part indices.

Returns:

cell_err_ok or < 0 on error (see cell_err).
