Fluid particles interactions with the ghost ones.

Compute the differential operators except the Laplacian of the velocity already computed, taking into account just the fluid-ghost interactions.

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.
r	Position \( \mathbf{r} \).
u	Velocity \( \mathbf{u} \).
rho	Density \( \rho \).
m	Mass \( m \).
p	Pressure \( p \).
refd	Density of reference \( \rho_0 \) (one per set of particles)
grad_p	Pressure gradient \( \frac{\nabla p}{rho} \).
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
g	Gravity acceleration \( \mathbf{g} \).
