Ghost particles Laplacian of the velocity computation.

This method compute the Laplacian of the velocity also in the mirroring boundary elements because such information will be required to extend the pressure field.

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 \( m \).
h_var	variable kernel lenght \( h \).
lap_u	Velocity laplacian \( \frac{\Delta \mathbf{u}}{rho} \).
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
