We present a new event generator based on the three-fluid hydrodynamics approach for early stage of collision, followed by particlization at hydrodynamic decoupling surface to join microscopic transport model, UrQMD, account hadronic final state interactions. first results nuclear collisions FAIR/NICA energy scan program (Au+Au collisions, $\sqrt{s_{NN}}=4-11$ GeV). address directed flow protons and pions as well proton rapidity distribution two model EoS, one with order phase transition other crossover type softening high densities. The simulation has unique feature that it can describe hadron-to-quark matter which proceeds in baryon stopping regime is not accessible previous programs designed higher energies.
