Fluid particles interactions computation.

Compute the differential operators involved in the numerical scheme, taking into account just the fluid-fluid interactions.

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 \( p \).
h_var	variable kernel lenght \( h \).
Omega	\( \Omega \) term.
grad_p	Pressure gradient \( \frac{\nabla p}{rho} \).
lap_u	Velocity laplacian \( \frac{\Delta \mathbf{u}}{rho} \).
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
