Welcome to the models and codes page of our group. We are interested in understanding electrochemical systems through mathematical modeling and simulation (Venkat Subramanian’s interest dates back to his undergraduate days when he worked on boundary element method for cathodic protection with Dr. Bosco Emmanuel).
In this page, you will find source codes (in Maple™/MATLAB®/FORTRAN) developed by our group for various models published by us and other researchers in the field of electrochemical engineering. The source codes are posted as a pdf document. Original source codes in the native platforms can be obtained by contacting Dr. Venkat Subramanian.
These codes developed were/are supported in part by the NSF projects (CTS 0609914, CBET-0828002, CBET-0828123, and CBET-1008692) and the US Government.
This page will be updated frequently with contributions from students and alumni of our group.
