Detailed Description

This material implements the weak statement of the three-dimensional compressible euler equations.

It is for transient analysis, finite volume method and explicit time integrator only.

Note: For Olivier Roussel's project.

Conservation Law:: $U_t(t, X) + \nabla \cdot F(U(t, X)) = 0$

Variables:: $U = (\rho, \rho * \upsilon_x, \rho * \upsilon_y, \rho * \upsilon_z, E)$
$\rho =$ density
$(\upsilon_x, \upsilon_y, \upsilon_z) =$ velocity
$\| \mbox{velocity} \| = \| v \| = \sqrt(\upsilon_x^2 + \upsilon_y^2 + \upsilon_z^2 )$
energy
pressure
specific heat at constant pressure of the gas
specific heat at constant volume of the gas.

Fluxes:: $F_x(U) = (\rho * \upsilon_x, \rho * \upsilon_x^2 + p, \rho * \upsilon_x * \upsilon_y, \rho * \upsilon_x * \upsilon_z, \upsilon_x (E + p))$
$F_y(U) = (\rho * \upsilon_y, \rho * \upsilon_x * \upsilon_y, \rho * \upsilon_y^2 + p, \rho * \upsilon_y * \upsilon_z, \upsilon_y (E + p))$
$F_z(U) = (\rho * \upsilon_z, \rho * \upsilon_x * \upsilon_z, \rho * \upsilon_y * \upsilon_z, \rho * \upsilon_z^2 + p, \upsilon_z (E + p))$

Equation of state:: $p = (\gamma - 1) \star (E - \frac{1}{2} \rho \| v \| )$
$\gamma = \frac{c_p}{c_V}$

Note: For tests we used $\gamma = 1.4$ .
