Dynamical freeze-out in event-by-event hydrodynamics

In hydrodynamical modeling of the ultrarelativistic heavy-ion collisions the freeze-out is typically performed at a constant temperature. The more physical choice is to use a criterion that freeze-out happens when the hydrodynamical expansion rate exceeds the scattering rate of particles. I'll show how this uncertainty in freeze-out criterion affects the anisotropies v_2 and v_3 in event-by-event calculations.
