Numerical models to analyze blood flow may be important for a better understanding of organ hemodynamics and (dys)function (e.g. in organ transplant research), and diagnostic techniques (e.g. contrast-enhanced MRI to characterize tumors). Existing models of (liver) vascular trees are predominantly based on idealized models using fractional calculus to describe bifurcating branching patterns. In contrast, we previously developed an electrical analog model of the human hepatic circulation, based on measured data of the macrocirculation and extrapolated data of the microcirculation [1]. Furthermore, the microcirculation is usually modeled as a porous medium [2].
