Dynamical freeze-out criterion in a hydrodynamical description of Au + Au collisions at $\sqrt{s_{\mathrm{NN}}}=200$ GeV and Pb + Pb collisions at $\sqrt{s_{\mathrm{NN}}}=2760$ GeV

In hydrodynamical modeling of ultrarelativistic heavy-ion collisions, the freeze-out is typically assumed to take place at a surface of constant temperature or energy density. A mo…
