freeslip()

__kernel void freeslip	(	const __global int *	imove,
		const __global vec *	r,
		const __global vec *	u,
		const __global float *	rho,
		const __global float *	m,
		__global vec *	lap_u,
		const __global uint *	icell,
		const __global uint *	ihoc,
		uint	N,
		uivec4	n_cells
	)

Compute the Laplacian of the velocity at the boundary, when free-slip boundary condition is considered.

Parameters

imove	Moving flags. imove > 0 for regular fluid particles. imove = 0 for sensors. imove < 0 for boundary elements/particles.
r	Position \( \mathbf{r} \).
u	Velocity \( \mathbf{u} \).
rho	Density \( \rho \).
m	Mass \( m \).
p	Pressure \( p \).
grad_p	Pressure gradient \( \frac{\nabla p}{rho} \).
lap_u	Velocity laplacian \( \Delta \mathbf{u} \).
div_u	Velocity divergence \( \rho \nabla \cdot \mathbf{u} \).
icell	Cell where each particle is located.
ihoc	Head of chain for each cell (first particle found).
N	Number of particles.
n_cells	Number of cells in each direction
