We introduce FluiduM, a code to simulate the quark-gluon plasma (QGP) formed in relativistic heavy-ion collisions. Based on a background-fluctuation splitting of the QGP and its initial conditions, in FluiduM the 2+1D hydrodynamic QGP evolution is replaced with a system of de-coupled 1+1D equations, leading to a reduction of orders of magnitude in computation time compared to more traditional codes. The framework implements state-of-the-art initial conditions, second order Israel-Stuart hydrodynamics, and QGP freeze-out supplemented with viscous corrections and resonance decays. We validate the code through calculations of particle yields and average hadron momenta. FluiduM provides a new powerful tool to test our understanding of heavy-ion collisions, with potentially far-reaching consequences for the realization of the goals of the heavy-ion collision program.
