Keynote Talks

During General Session presentations, world-leading researchers and engineers share their journeys of discovery and progress through precision multiphysics simulation. Attendees will also hear from the makers of COMSOL, who will share insight into their vision and present sneak previews of upcoming versions of the software.

Marco Cati, Esaote

Piezoelectric Transducers and Ultrasound Imaging: Impact of Materials Properties and Multiphysics Aided Design

Marco Cati graduated cum laude and encomium citation in electronic engineering in 2001 from the University of Florence, where in 2005 he also received a Ph. D. degree in electronic engineering. In 2005 he joined the Research & Development Department of Esaote where he is currently in charge of electromagnetic compatibility (EMC) design and testing activities on ultrasound and magnetic resonance devices. Dr. Cati is a member of IEEE and also an expert member of the IEC MT23 committee for the maintenance and development of IEC 60601-1-2 international standards. Since 2011 Dr. Cati serves as technical inspector for ACCREDIA (Italian Accreditation System). Dr. Cati is the author for over 50 scientific and technical works published in international journals and conference proceedings. Read Abstract


Medical ultrasound imaging has gone through many great advances and continues to provide ever more detailed diagnostic information. With the help of new ultrasound probe technology and signal processing, it’s possible to greatly increase sensitivity, bandwidth, field of view and other key parameters. Bandwidth, in particular, is important: it provides not only better image quality and diagnostic power by supporting many different frequency bands, but also means that doctors need fewer probes for standard diagnostic examinations. Thanks to a multiphysics simulation approach, probe design is undergoing new advances, as the level of optimization and understanding of the interaction between material properties and probe geometry is achieved. These simulations also support measurements prototype validation.

Examples of actual imaging probe characterization will be discussed and the role of multiphysics modeling within Esaote’s Research & Development Department will be outlined. A brief overview of the present, past and near future of diagnostic imaging will be also presented and a point of view about how COMSOL Multiphysics aided design and simulation has been integrated in the development process of Esaote’s ultrasound imaging systems will be shared with the audience.

Matthias Richwin, KOSTAL

Multiphysics Simulations in Automotive Product Development: Concept and Beyond

Matthias Richwin joined KOSTAL, a worldwide automotive first-tier supplier, in 2003 where he started working on the design of optical sensor systems. In 2007 he took over responsibility for simulation methods in the series product development and since then leads the simulation engineering group. Besides his interest in the haptics of car-driver interfaces, his main focus is currently on multiphysics simulations, HPC integration and simulation process development. Dr. Richwin received his Diploma in Experimental Physics in 1999 from RWTH Aachen in the field of X-ray focusing and imaging optics. Working on instrumentation for X-ray absorption spectroscopy with synchrotron radiation, he earned his doctor's degree at the University of Wuppertal in 2003. Read Abstract


KOSTAL develops and produces automotive interior switches, sensors and power electronics as a first-tier supplier for many major OEMs in the world. Years ago a man-machine interface in the car was mainly a mechanical construction which fulfilled basic switching functions and haptic feedback requirements. Today complex modules include - apart from the input device functions - numerous electronic functions, symbol illumination and lighting applications. In a current trend, we minimize the number of moving parts in the switch component, replacing mechanical buttons and contacts by capacitive sensors. In the field of electronics, high-power applications with high requirements show up in electronics for hybrid or battery electric vehicles. Further, with the plug at the end of the cable being the largest drawback of plug-in electric vehicles, inductive power transfer for contactless semi-automatic charging gains growing interest. The successful development and production of such products require a deep understanding of the underlying physics in a true mechatronic development process. The integration of multiphysics simulations in the product development process will be shown, followed by examples of the use of COMSOL in power electronics design, thermal analysis and capacitive sensors.

Tim Poole, JDR Cable Systems

Testing and Analyzing Complex Loading Conditions and Designs to Improve Subsea Cable Life

Tim Poole graduated from Cambridge University with a Masters degree in Engineering in 2008 and immediately joined JDR Cables Systems, a leading supplier of custom subsea oil and gas umbilical systems and renewable energy cables. He started in the Research and Development team, working on creating new products lines and testing umbilicals, which included fatigue, tensile and bend stiffness testing. He was then leading the introduction of FEA analysis of the umbilicals, focusing mainly on the mechanical and thermal characteristics. Read Abstract


In the ever increasingly demanding subsea oil and gas and renewable areas, products such as umbilicals and cables need to be rigorously tested to ensure that they do not fail in service. This requires extensive practical testing which are costly and in some cases can take over a month to complete. The alternative is to perform a FEA study that can analyze these products much quicker and can allow for a greater amount of information. However, due to the nature of the products, which can contain multiple contra-helical components, they are highly complex mechanical systems. This involves several thousand contact points and various material types. Therefore, JDR initiated a project with COMSOL certified consultant “Continuum Blue” to provide a solution to quickly analyze any type of umbilical. Such a solution can assess the details of any umbilical and automatically generate a 3D model including physics, mesh and material properties. As a result of this project, JDR now has the capability to perform in depth analysis of any umbilical or cable: this led to a quick review of all designs and to find the best candidate design in about a quarter of the time and for about half the cost.
