This article aims to develop a method to automatically generate CFD-based compartment models. This effort to simplify mixing models aims at capturing the interactions between material transport and chemical/biochemical conversions in large-scale reactors. The proposed method converts the CFD results into a system of mass balance equations for each defined component. https://www.roneverhart.com/NeOn-Zero-Lefty-M390-BLADE-TITANIUM-HANDLE-MRBS-p11472/
