The use of floating bipolar electrodes in copper electro-winning cells represents an emerging technology that promises economic and operational impacts. This thesis presents EWCellCAD, a computational tool designed for the simulation and analysis of these electrochemical systems. Based on the generalization and optimization of an existing 2D finite difference model for calculating electrical variables in rectangular cells, EWCellCAD implements a new 3D model capable of processing complex geometries, not necessarily rectangular, which also accelerates calculations by several orders of magnitude. At the same time, a new analytical method for estimating potentials in floating electrodes is introduced, overcoming the inaccuracies of previous heuristic approaches. The analysis of the results is supported by an interactive visualization technique of three-dimensional vector fields as flow lines.
