Function Documentation

entry()

__kernel void entry	(	const __global int *	imove,
		const __global vec *	r,
		const __global vec *	normal,
		const __global vec *	u,
		const __global float *	m,
		__global vec *	grad_w_bi,
		__global float *	div_u_bi,
		usize	N,
		LINKLIST_LOCAL_PARAMS	)

Compute the boundary integrals.

Parameters

imove	Moving flags. imove > 0 for regular fluid particles. imove = 0 for sensors. imove < 0 for boundary elements/particles.
r	Position \( \mathbf{r} \).
normal	Normal \( \mathbf{n} \).
u	Velocity \( \mathbf{u} \).
m	Area of the boundary element \( s \).
grad_w_bi	Gradient of constant fields due to the boundary integral \( \langle \nabla 1 \rangle^{\partial \Omega} \).
div_u	Velocity divergence \( \nabla \cdot \mathbf{u} \). Actually this is just the part that has to do with the boundary element velocity
N	Number of particles.
icell	Cell where each particle is located.
ihoc	Head of chain for each cell (first particle found).
n_cells	Number of cells in each direction

p_boundary()

__kernel void p_boundary	(	const __global int *	imove,
		const __global vec *	r,
		const __global float *	m,

		__global float *	p,
		usize	N,
		LINKLIST_LOCAL_PARAMS	)

Compute the pressure on each boundary element.

Parameters

imove	Moving flags. imove > 0 for regular fluid particles. imove = 0 for sensors. imove < 0 for boundary elements/particles.
r	Position \( \mathbf{r} \).
m	Particle mass \( m \).
rho	Particle density \( \rho \).
p	Particle pressure \( p \).
N	Number of particles.
icell	Cell where each particle is located.
ihoc	Head of chain for each cell (first particle found).
n_cells	Number of cells in each direction
