Parameters

GP_energy_degradpdt	Energy induced by the ghost particles due to the pressure term.
GP_energy_dedivudt	Energy induced by the ghost particles due to the compressibility.
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 \( \mathbf{r} \).
u	Velocity \( \mathbf{u} \).
rho	Density \( \rho \).
p	Pressure \( p \).
m	Mass \( m \).
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
GP_energy_iset	Ghost particles set to be considered.
