Detailed Description

Algorithm based on the Godunov-type Scheme (explicit). We use a two-time steps integrator belongs to Runge-Kutta family and the HLL algorithm for convective flux evaluation. Order is achieved by MUSCL reconstruction procedure to extrapolate state variables at cell face j+1/2 (piecewise-constant state variable on each cell). This algorithm solve at cell-face a Riemann problem (system of conservation law coupled with 2-state tied by a discontinuity define a Riemann Problem).
