MLS based correction term, due to the particles at the other portal side.

The term computed with this function should be later renormalized by MLS.

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 \( \mathbf{r} \).
rmirrored	Mirrored position of the particle, r if imirrored is false (0).
rho	Density \( \rho \).
m	Mass \( m \).
p	Pressure \( p \).
lap_p_corr	Correction term for the Morris Laplacian formula.
icell	Cell where each particle is located.
ihoc	Head of chain for each cell (first particle found).
