Over the last decade, the modeling of aluminum reduction cell energy balance has evolved significantly from the use of 2D in-house codes to the adoption of 3D commercial codes such as ANSYS® finite element models. This paper reviews the advantages and disadvantages of various 3D modeling tools, including 3D cathode slices, half anodes, and full cell models, while also revisiting the 2D model to propose an improved approach. The research investigates the critical role of thermo-electric design in influencing power consumption characterized in kWh/kg of aluminum produced and its direct impact on cell lining life. Notably, enhancing the thermo-electric design is identified as a key factor in optimizing smelter operations, providing an inexpensive yet effective avenue for achieving substantial returns on investment during retrofitting projects. Despite the complexity of the Hall-Héroult electrolysis process, this study indicates the importance of reliable mathematical modeling and theoretical analysis, given the multitude of interconnected physical and chemical phenomena involved. Ultimately, this exploration highlights the need for continual improvement in the design processes employed within the aluminum reduction industry.
