< <  The method parameterizes the matter flow in terms of discrete Lagrangian coordinates, called SPH particles. In terms of SPH degrees of freedom, the equations of motion can be derived by using the variational principle. The main advantage of the method is that it is rather robust to deal with any kind of geometrical structure and violent dynamics. For example, shock wave phenomena can be treated without numerical difficulty, provided the size of SPH particles is appropriately chosen.

Initial conditions (IC)  
Changed:  
< <  Hydrodynamic models employ the hypothesis that hot and dense matter created in collisions reaches at a certain instant a local thermal equilibrium, after which it expands and cools down before particle emission takes place. Such a local thermal equilibrium is usually characterized by some IC, which can be expressed in terms of distributions of the fluid velocity and of thermodynamical quantities for a given timelike parameter.

Equation of state (EOS)  
Changed:  
< <  In order to close the system of hydrodynamic equations, one also needs the EOS of the fluid, which describes the thermodynamic property of the fluid. In SPheRIO, several sets of predefined EOS are at disposal. The first set of EOS makes use of hadronic resonance model with finite volume corrections to describe the matter on the hadronic side, and MIT bag model for quark gluon plasma (QGP) phase. The main part of observed resonances in Particle Data Tables are included in the hadronic phase. Others include EOS inspired by lattice QCD data and EOS taking into account local strangeness neutrality. Also some simple EOS are provided for testing purposes, for instance, a set of analytic EOS which assumes a massless pion gas in the hadronic phase and the MIT bag model in the QGP phase.
