Function Documentation

iCell()

__kernel void iCell	(	__global usize *	icell,
		const __global vec *	r,
		const usize	N,
		const vec	r_min,
		const float	support,
		const float	h,
		const svec4	n_cells )

Compute the cell where each particle is allocated.

Parameters

icell	Cell where each particle is allocated.
r	Position \( \mathbf{r} \).
N	Number of particles.
r_min	Minimum of r.
support	Kernel support as a factor of h.
h	Kernel characteristic length.
n_cells	Number of cells at each direction, and the total number of allocated cells.

Here is the call graph for this function:

iHoc()

__kernel void iHoc	(	__global usize *	ihoc,
		usize	N,
		svec4	n_cells )

Set all the cells as empty (i.e. the head of chain of the cell is a particle that does not exist).

Parameters

ihoc	Head of chain of each cell.
N	Number of particles.
n_cells	Number of cells at each direction, and the total number of allocated cells.

linkList()

__kernel void linkList	(	const __global usize *	icell,
		__global usize *	ihoc,
		const usize	N )

Compute the linklist after the sort of the icell array.

Parameters

icell	Cell where each particle is allocated.
ihoc	Head of chain of each cell.
N	Number of particles.
