Amine Amimi is working as a Development Engineer in the equipment engineering division at Tetra Pak where he supports the development of new products and solutions in the food packaging industry by performing thermal and structural FE analyses of processes and components.
Amine joined Tetra Pak in 2015 after graduating from the University of Trento in the same year with a Master’s degree in Material Science and Engineering.

Amine’s first approach to simulation methods and tools started 10 years ago in the molecular dynamics field through the development of atomistic models used to predict and study X-ray diffraction patterns of novel materials. He later moved to the structural finite element field in which he’s still an extensive user of SIMULIA’s applications, mainly involving ABAQUS and ISIGHT.

His current research interests are in the latest and innovative approaches to modelling and simulation relying on data-driven and machine-learning methods which have deeply fascinated him in the last years.

I graduated at Politecnico of Milan, where I achieved also a Ph.D. in Structural, Earthquake and Geotechnical Engineering. My thesis was on the modeling of the forming technologies employed by Tetra Pak in its liquid food packaging business, so it has been natural for me to join the company when I left the academia in 2010. During my studies I grew a strong interest for FEM and numerical methods, especially in the field of shell modelling. I collaborated to the implementation of the nonlinear shell model in the commercial solver Xfinest. The project I loved the most was the collaboration with MOX department in Milan for the modelling of the Wind – Sail FS Interaction. Since 2010 I am a Development Engineer in Tetra Pak, my job focusing on the numerical modeling of complex packaging material – machine - product interactions. My daily work as analyst in R&D revolves around the use of Abaqus, the software I first met as a student at university and on which I have grown most of my experience.

My hobbies are photography and board games.

Andreas K. Bitz is Professor of Electromagnetic Theory and Applied Mathematics in the Department of Electrical Engineering and Information Technology at FH Aachen - University of Applied Sciences, Aachen, Germany.

Andreas Bitz received the Ph.D. (Dr.-Ing.) in electrical engineering from the University of Wuppertal, Germany. He worked as a post-doctoral fellow at the Erwin L. Hahn Institute for MRI, Essen, Germany, and in the Division of Medical Physics in Radiology at the German Cancer Research Center (DKFZ) in Heidelberg, Germany.

For almost 25 years, Andreas Bitz is using CST Studio Suite for electromagnetic and bioheat transfer simulations, often by employing high-performance computing and user-defined post-processing routines.

He is working in collaboration with partners from academia and industry in the field of ultra-high field magnetic resonance imaging, with focus on MRI safety, implant safety and compliance testing of multi-channel RF coil arrays including experimental validation of numerical results.

He is teaching undergraduate and graduate courses in Electromagnetic Modelling and Simulation as well as Electromagnetic Field Theory where students utilize CST Studio Suite to analyze the characteristics of electromagnetic fields in basic and complex geometries.

I am RF Engineering Team lead at ALCAN Systems GmbH where we work on developing phased array antennas using Liquid Crystal technology. Phased arrays are considered the pinnacle of antenna engineering because they are challenging theoretically, numerically and practically. In other words, from first concept to simulations to prototyping, phased array antennas require tremendous attention to detail. For proper design, a lot of simulations of smaller components are required which need to be combined afterwards. CST, with its suite of different solvers, provides a lot of flexibility to the design engineer. Different solvers are also extremely useful for convergence and sanity checks.

I hold a Bachelor of Science degree from COMSATS University Abbottabad Pakistan, Master of Science and PhD degrees from Technical University of Darmstadt. It was during my PhD studies back in 2011 when I started working with CST. My research topic was Dielectric Resonator Antennas for which I used CST's TD and FD solvers extensively. Today at ALCAN, I still spend all my day in front of CST. The ever-expanding features in every release from CST aids in handling the complex simulations. For example the Schematic features, have also begun to play a critical role in our design because they simplify complex system simulations.

RF/Microwave components and systems of today are so complex that designing them with pen and paper is nearly impossible. That is why tools like CST Microwave Studio are indispensable not only for practicing RF/Microwave and Antenna engineers like ourselves, but also for students to grasp intricacies of Electromagnetism by providing valuable insights. This intuition and understanding is key to becoming a great at RF/Microwave design, which is not called black magic for no reason.

I look forward to helping others while also advancing my knowledge in the Simulia/CST community platform.
