Abstract: In this proceedings contribution, the qualitative effect of a net baryochemical potential dependence of the shear viscosity to entropy density ratio η/sη/s in hybrid approach simulations is investigated. The influence of a net baryochemical potential dependence of the shear viscosity over entropy ratio on the observables of heavy-ion collisions has been subject of only few investigations in hydrodynamic simulations. In this work, a generalized η/sη/s (T,μBT,μ B​) is tested within the hybrid approach SMASH-vHLLE-hybrid, combining the hadronic transport approach SMASH and the (3+1)D viscous hydrodynamic code vHLLE. It is shown that the proposed parameterization approximates the shear viscosity in the late stage non-equilibrium hadronic transport stage.
