We report on construction of a modern multi-fluid approach to heavyion collisions at FAIR/BES energies (MUFFIN) and show the reproduction of basic experimental observables in Au-Au collisions in the RHIC Beam Energy Scan program. We also show the pT-differential and pT-integrated polarization of (anti-)A hyperons. In MUFFIN simulations, we observe a strong splitting between polarizations of A and anti-A. The splitting is driven purely by a finite baryon chemical potential.
