This file contains the configuration structures for different Riemann solver types used in Godunov SPH (GSPH). The Riemann solver computes the interface pressure (p*) and velocity (v*) at particle-particle interfaces.

The GSPH method originated from:

• Inutsuka, S. (2002) "Reformulation of Smoothed Particle Hydrodynamics with Riemann Solver"
