Tool to compute the fluid energy components.

Actually, in this kernel the energy componets variation are computed per each particle.

Parameters

energy_dekindt	Variation of the kinetic energy: \( \frac{dE^{kin}_a}{dt} = m_a \mathbf{u}_a \cdot \frac{d \mathbf{u}_a}{dt}\)
energy_depotdt	Variation of the potential energy: \( \frac{dE^{pot}_a}{dt} = - m_a \mathbf{g} \cdot \mathbf{u}_a\)
energy_decomdt	Variation of the compressibility energy: \( \frac{dE^{com}_a}{dt} = \frac{m_a}{\rho_a} \frac{p_a}{\rho_a} \frac{d \rho_a}{dt} \)
imove	Moving flags. imove > 0 for regular fluid particles. imove = 0 for sensors. imove < 0 for boundary elements/particles.
u	Velocity \( \mathbf{u} \).
rho	Density \( \rho \).
m	Mass \( m \).
p	Pressure \( p \).
dudt	Velocity rate of change \( \frac{d \mathbf{u}}{d t} \).
drhodt	Density rate of change \( \frac{d \rho}{d t} \).
N	Number of particles.
g	Gravity acceleration \( \mathbf{g} \).
