Performs the boundary effect on the fluid particles.

Parameters

iset	Set of particles index.
imove	Moving flags. imove > 0 for regular fluid particles. imove = 0 for sensors. imove < 0 for boundary elements/particles.
imirrored	0 if the particle has not been mirrored, 1 otherwise.
r	Position \( \mathbf{r} \).
rmirrored	Mirrored position of the particle, r if imirrored is false (0).
normal	Normal \( \mathbf{n} \).
nmirrored	Mirrored normal of the particle, normal if imirrored is false (0).
u	Velocity \( \mathbf{u} \).
umirrored	Mirrored velocity of the particle, u if imirrored is false (0).
rho	Density \( \rho \).
p	Pressure \( p \).
mass	Mass \( m \).
refd	Density of reference \( \rho_0 \) (one per set of particles)
grad_p	Pressure gradient \( \nabla p \).
div_u	Velocity divergence \( \nabla \cdot \mathbf{u} \).
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
g	Gravity acceleration \( \mathbf{g} \).
