Pressure interpolation at the boundary elements.

The values are computed using just the fluid information. The resulting interpolated values are not renormalized yet.

Just the elements with the flag imove = -3 are considered boundary elements.

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 \( \mathbf{r} \).
m	Mass \( m \).
rho	Density \( \rho \).
grad_p	Pressure gradient \( \frac{\nabla p}{rho} \).
p	Pressure \( p \).
icell	Cell where each particle is located.
ihoc	Head of chain for each cell (first particle found).
refd	Density of reference of the fluid \( \rho_0 \).
N	Number of particles.
n_cells	Number of cells in each direction
