Tool to compute the fluid energy components.

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

Parameters

energy_ek	Kinetic energy: \( E^{kin}_a = \frac{1}{2} m_a \vert \mathbf{u}_a \vert^2\)
energy_ep	Potential energy: \( E^{pot}_a = - m_a \mathbf{g} \cdot \mathbf{r}_a\)
energy_ec	Compressibility energy: \( E^{com}_a = m_a c_0^2 \left( \frac{\rho_0}{\rho_a} + \log(\rho_a) \right) \)
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 \( \rho \).
m	Mass \( m \).
N	Number of particles.
g	Gravity acceleration \( \mathbf{g} \).
cs	Speed of sound \( c_s \).

Tool to compute the fluid energy variation rate components.

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

energy_depdt	Variation of the potential energy: \( \frac{dE^{pot}_a}{dt} = - m_a \mathbf{g} \cdot \mathbf{u}_a\)
energy_decdt	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 \( \frac{d \rho}{d t} \).
