  We present a new event generator based on the three-fluid hydrodynamics (3FH)
approach, followed by a particlization at the hydrodynamic decoupling surface
and a subsequent UrQMD afterburner stage based on the microscopic UrQMD
transport model that accounts for hadronic final state interactions. First
results for Au+Au collisions are presented. The following topics are addressed:
the directed flow, transverse-mass spectra, as well as rapidity distributions
of protons, pions and kaons for two model equations of state, one with a
first-order phase transition, the other with a crossover transition.
Preliminary results on the femtoscopy are also discussed. We analyze the
accuracy of reproduction of the 3FH results by the new event generator and the
effect of the subsequent UrQMD afterburner stage.
