Keynote Talks at the COMSOL Conference 2017 Rotterdam
If you would like to see firsthand how experts from industry are using multiphysics modeling to innovate, be sure to attend the keynote talks at the COMSOL Conference 2017 Rotterdam. After each talk, you have the opportunity to connect with the speaker and ask questions about their presentation. The Keynote session also features sneak previews of future versions of COMSOL Multiphysics®.
Svante Littmarck is the President and CEO of COMSOL, Inc. He cofounded the COMSOL group in 1986. In 2004, Littmarck received an honorary doctoral degree from the Royal Institute of Technology for the development and international reach of high quality software for scientific computations through his company COMSOL.
Paving the Way Toward Invisible Hearing Implants
While most hearing aids carry sounds through the ear canal to the middle ear, the fully implantable Carina® System connects with the structures of the middle ear and carries sounds directly to the inner ear. During this talk, it will be demonstrated how the COMSOL Multiphysics® software was used to support the development of the different system components: a subcutaneous microphone that captures the sound through the skin, the MicroDrive™ actuator that drives the ossicles, and the inductive link to power the implant.
Carina and MicroDrive are trademarks or registered trademarks of Cochlear Limited.
After his PhD in Bioscience Engineering at KU Leuven (Belgium), Patrik Kennes worked for 7 years at Tenneco Automotive where he was involved in the controller development for the Continuously Variable Semi-Active Damping System (CVSA) that continuously adjusts damping levels according to road conditions and vehicle dynamics. Currently he works at the Cochlear Technology Centre where he is leading the CAE activities for the development of implantable hearing solutions. Key expertise areas are micro-actuator design, structural dynamics and acoustic-structure interaction.
Finite Element Analysis for Loudspeaker Drivers and Systems: “Where and Why?”
In this presentation, we will look at the big picture of all of the physics involved when designing a loudspeaker driver or system. We will then focus on some (mechanics, acoustics, fluid dynamics, etc.) to see where finite element analysis can be used through standard or optimization methods. We will finally look at what the simulation strategy is and what the benefits can be for an organization to use COMSOL Multiphysics®.About the Speaker
Mathieu Pobeda was born in Mazamet, France. He studied signal processing and RF at Université Paul Sabatier in Toulouse and at Conservatoire National des Arts et Métiers in Saint Etienne, where he graduated with a master's degree. He joined NEXO in 2011 as a systems design engineer. His interests include transducer and system design, materials science, and sound recording. He is also a keen guitarist and has a great interest in history (in general and of music in particular) and geopolitics.
Multiphysics Simulation (Beyond Semiconductors) at STMicroelectronics, Italy
Microelectronic systems are permeating more and more into our daily life, giving rise to new challenges for technology designers, who must interface their devices with the macroscopic world and sometimes embed them in severe environments. This talk is an overview of how multiphysics simulation is exploited at STMicroelectronics, Italy, to face this scenario in different contexts, including die-package interaction analysis and sophisticated wearable systems design as well as an epitaxial reactor thermofluidic simulation and a force sensor for a concrete integrity monitoring study. A thermomechanical simulation example will be detailed as a test case.
Lucia Zullino received the laurea degree in condensed matter physics from the University of Pavia in 1982. After one year of postgraduate work at the University of Pavia and three years spent with an aeronautical firm, she joined STMicroelectronics. There, she was committed to technology CAD activities within the mixed bipolar-CMOS-DMOS technology design group, contributing to the development of several smart power technological nodes. She became a COMSOL Multiphysics® user in 2004 and, starting from 2008, she coordinates the Italian COMSOL® software user group at STMicroelectronics. As of 2009, she is a senior member of their technical staff. She manages, at present, the T-CAD Competence Center of the Smart Power Technology R&D Department.
Lucrezia Guarino has been a FE-BE compatibility engineer at STMicroelectronics since 2013, working on smart power technology platforms. She supports the development and optimization of thermomechanical simulation setups dedicated to study, on a theoretical basis, the interaction between chip and package, driving from this standpoint the selection of materials both in FE and in BE. She has a master’s degree in materials science from the University of Milano Bicocca.
CFD Integrated in the Design of Complex Hydraulic Structures
Over the past decade, the increase in model quality and computer power has made it possible to apply computational fluid dynamics to hydraulic structures on a much larger scale. It is accepted more and more by our field and our clients as an essential tool in the design of new hydraulic structures, like navigation locks, discharge facilities, spills, and bridges. CFD is used to optimize a design and to prove that it meets the requirements of the client. In this presentation, we will show how CFD is integrated in several projects at Witteveen+Bos and how it innovates the design process.About the Speaker
Arie de Niet is a data scientist and CFD expert at Witteveen+Bos. In 2007, he received a doctoral degree (PhD) at the University of Groningen for his research on fast solution of ocean-climate models. After his PhD, he joined Witteveen+Bos, where he developed extensive knowledge in applying statistics and CFD in a wide range of fields. Due to his background and experience, he is able to apply CFD in a practical context for both water treatment and hydraulic structures. He is familiar with the limitations and the risks but also the power and the beauty of CFD.
