“Athena Visual Studio is a powerful and versatile program that I am using for modeling dynamic reactor performance and to fit complex kinetic models to experimental data sets. It allows you to build a working model quickly, without the need for programming expertise, but is also sufficiently flexible to permit you to insert custom Fortran code when needed. I have used the program for over 15 years and have yet to encounter a comparable program that meets my needs just as well.”

“Athena Visual Studio combines strong and efficient numerical solvers with straightforward syntax coding and GUI. This allows also non-experts to solve complex chemical engineering problems. I am a happy user of the package for both consultancy and teaching since almost 20 years.”
Rob Berger - Consultant in Catalysis & Reactor Engineering and Reaction Kinetics
"Fast and versatile. Athena lets us carry out complex mathematical and chemical analyses with ease. The standout features are the parameter estimation and the excel link"

“Athena Visual Studio is a powerful yet convenient tool for Chemical Engineering practitioners to use for the development of Differential and Algebraic Equation (DAE) models for simulation purpose. Additionally, built upon classical theoretical foundation laid out by the late Professor Warren Stewart at the University of Wisconsin, Athena Visual Studio provides the most robust parameter estimation toolbox, GREGPLUS, that the user has ever used to estimate parameters using experimental data in my industrial practice. I strongly recommend this tool to anyone who has the need to develop models and conduct parameter estimation in chemical industry."

"We regularly use Athena for parameter estimation in catalytic reaction models. It is a powerful and user-friendly tool that helps us develop meaningful reaction-diffusion models that accurately describe observed reaction rates in micro/mesoporous zeolite catalysts."
