“In our work of chemical conversion and storage of energy, Athena Visual Studio has been an important tool already for years; we have successfully used this software in several PhD theses at the Swiss technical universities. For us, the most important aspect is - besides the numerical quality - the fact that one tool covers all our problems from parameter estimation in the evaluation of kinetic data from the laboratory up to rate based models of catalytic reactors which are validated by pilot scale data and applied in thermo-economic process chain analyses.”

“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.”

"We use Athena to derive fundamental models for complex gas-solid reactions from experimental data. The statistical analysis features are user-friendly and are a critical research tool for discriminating which models best describe the data."

“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."

"Athena Visual studio plays a critical role in my research group's efforts to quantify the kinetics of heterogeneous catalytic reactions, by providing reliable tools for parameter estimation, error analysis, and optimal experimental design."
