Particles interactions computation.

Compute the rates of variation due to the fluid (fixed particles will be included here).

During this stage some other operations are performed as well, like the values interpolation in the boundaries (for DeLeffe boundary conditions), the sensors meassurement, or the Shepard factor computation.

Parameters

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 \( \mathbf{r} \).
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
