A Generic I-BIEM Code for Electrochemical Problems

Abstract

A generic computer code based on the iterative boundary integral equation method (I-BIEM) is developed for simulating a variety of electrochemical problems. In this work we have extended the reach of the method by developing a generalized program capable of solving a wide range of electrodeposition problems. The new code accommodates quite easily multi-variable problems including those with curved boundaries, and non-linear boundary conditions. Such problems include anomalous codeposition of alloys, incorporating the effects of convective and diffusive mass transport; time variant effects such as would be observed in extended growth calculations and pulse plating; microstructural modeling with reference to nonisotropic boundary conditions and crystallographic effects. Some interesting results of real-life simulations are presented. The code is an excellent method for solving problems with huge coefficient matrices. The scheme avoids the use of large computer storage spaces and a direct inversion of the matrices is also not required. The result is a considerable improvement over existing boundary integral equation schemes in terms of computer running time and accuracy for problems especially those with complex shapes and boundary conditions.
