The new electrochemical simulation component of AfterMath Electrochemical Studio is an exciting and highly requested feature. Our goal is to provide an integrated solution into our already powerful AfterMath Electrochemical Studio software application. There are inherent benefits in only having to use one single application to acquire experimental data, fit those data, analyze, and plot, and now simulate. By integrating these components into a single application, it saves time and hassle as users do not have to import/export across more than one application.
Other electrochemical simulation software exists at various price points and capabilities. Some of these options might be free but lack in features or flexibility and have little to no support. Others might be full featured, yet costly, and are not well-developed or user-friendly for a broad audience, like newcomers to electrochemistry. A team of Pine Research electrochemical scientists and software engineers actively support AfterMath Electrochemical Studio.
2Simulation Engine Development
The electrochemical simulation engine employs fast quasi-explicit finite difference (FQEFD) for semi-infinite linear diffusion utilizing an exponentially expanding space grid (based on the DuFort-Frankel algorithm).
This method has been found to give highly accurate results as compared to theory. It is particularly effective for dealing with mathematically stiff problems, which involve large values of one or more homogenous rate constants and/or a wide dynamic range of homogenous rate constants. The FQEFD method enhances the computational speed by several orders of magnitude as compared to the traditional fast implicit finite difference (FIFD) method.
In using any new software, users might be skeptical or uncertain about what the software reports. We have found it very helpful to compare the output from our simulation software to the classic examples found in the 3rd Edition of Electrochemical Methods by Bard, Faulkner, and White.
We simulated the many examples from Electrochemical Methods in AfterMath Electrochemical Studio.
The plots were customized (colors, weights, fonts, etc.) in AfterMath to resemble the examples in the text. In all cases, the output from our simulations exactly matches the cases provided in the text.
