Implementation and testing of a hypersurface finder for event-by-event (3+1)D hydrodynamics

Hydrodynamic simulations of nuclear collisions can model the expansion and cooling of the fireball created in such collisions. Many applications require a fast and efficient algorithm to find and parameterize hypsersurfaces; e.g. the isothermal surface at the freeze-out temperature can be used to calculate a final distribution of particles in the collision via the Cooper-Frye procedure. An algorithm proposed by Pang, Wang, and Wang is evaluated and compared to standard algorithms in AZYHYDRO and Cornelius.
