“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 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."

Eighteen years ago, I started to use Athena for developing a sophisticated methodology of multi-parameter estimation for the characterization of the pore structure of catalyst carriers. Since then, Athena has been a valuable tool for our research concerning, among others, the migration of pollutants in subsurface and study of advanced methods of soil and groundwater remediation. It’s worth mentioning the extensive use of Athena for the multi-scale numerical simulation of multiphase transport and reactive processes in porous media, and inverse modeling of datasets from relevant laboratory experiments.

"For us Athena for is an essential tool for propriety model development and distribution. In our applications Athena proved to be very robust in large parameter estimation tasks. We benefitted from the easy way of adding own Fortran code. Distribution of the developed models by means of Excel DLL's pushed the use of models throughout R&D and Sales departments. Fast and to the point support of Michael himself was very helpful".

"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."
