An extension of Godunov SPH: Application to negative pressure media

The modification of Smoothed Particle Hydrodynamics (SPH) method with Riemann Solver is called Godunov SPH. We further extend the Godunov SPH to the description of a medium with negative pressure. Under certain circumstances, the SPH method shows an unphysical instability that results in particle cl...
