Detailed Description

Mirroring process for the symmetry boundary condition.

Function Documentation

cell()

usize cell	(	vec	r,
		vec	r_min,
		float	h,
		svec4	n_cells )

Compute the cell where the particle is allocated.

Parameters

r	Position \( \mathbf{r} \)
r_min	Minimum of r (considering all the particles).
n_cells	Number of cells at each direction, and the total number of allocated cells.

mirror()

__kernel void mirror	(	__global vec *	r,
		__global int *	imirrored,
		__global usize *	icell,
		usize	N,
		vec	portal_in_r,
		vec	portal_out_r,
		vec	portal_n,
		vec	r_min,
		float	h,
		svec4	n_cells )

Compute the mirrored position of the fluid particles.

The mirrored particles (the ones close enough to the out portal plane) will be marked with imirrored = 1.

Parameters

r	Position \( \mathbf{r} \)
imirrored	0 if the particle has not been mirrored, 1 otherwise.
icell	Cell where each particle is allocated.
N	Number of particles
portal_in_r	In portal infinite plane position
portal_out_r	Out portal infinite plane position
portal_n	Portal infinite planes normal
r_min	Minimum of r.
n_cells	Number of cells at each direction, and the total number of allocated cells.
