CCAKE

CCAKE is a relativistic viscous hydrodynamic code with 3 conserved charges (baryon number, strangeness, and electric charge) that uses Smoothed Particle Hydrodynamics. CCAKE can make state-of-the-art predictions for heavy-ion collisions and follows a multi-stage approach that includes initial conditions -> hydrodynamics -> freeze-out -> particle decays. It uses the 4D lattice QCD equation of state with T, baryon, strangeness, and electric charge that is coupled to the PDG16+.
