N2 - In this paper, we propose a method for numerical modeling of the nuclear matter properties within the framework of relativistic heavy-ion collisions using a holographic equation of state. Model’s free parameters are calibrated using lattice results for quark masses approximating physical values and adjusted to match the Regge spectra of ρ mesons. Numerical simulations are performed using the iEBE-MUSIC framework, which incorporates the MUSIC relativistic hydrodynamics solver. We modify the code by implementing a tabulated holographic equation of state, enabling simulations of quark–gluon plasma evolution with dynamically generated initial conditions via the 3D Monte Carlo Glauber Model. Finally, the spectra of produced hadrons are computed using a hybrid iSS + UrQMD approach at the freeze-out stage.
