Customer Testimonials

"Athena provides a quite integrated and powerful environment to carry our modelling, parameter estimation and optimisation of chemical engineering processes. Especially in the field of reaction engineering there are a multitude of tools and examples available to allow research students to become productive quite quickly. The interface is very user friendly and simplifies the programming tasks, e.g. in relation to the discretisation of partial differential equations, considerably. More experienced programmers can further utilise the underlying FORTRAN to implement more complex models or interface with existing codes they might have developed in the past."
Dr Panagiotis Kechagiopoulos - Lecturer in Chemical Engineering, University of Aberdeen
“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.”
T.J. Schildhauer - Senior Scientist in the Laboratory for Thermal Processes
Paul Scherrer Institut, Switzerland

"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."
Michael Tsapatsis, Ph.D. - Professor
Department of Chemical Engineering and Materials Science
University of Minnesota
“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."
Min Zhang - Axalta Coating Systems

“Athena Visual Studio is an excellent tool for our PhD and MSc research and education for Food Technology students. It’s extremely versatile for estimation parameters of processes and (bio)chemical reactions related to food.”
