Building a Better Pump for Heart Failure Patients
Abbott’s Mechanical Circulatory Support group build implants that help people suffering from heart failure, a deadly and increasingly common disease. We combine computational fluid dynamics and particle tracing simulations to optimize the designs of implantable blood pumps that replace the left heart function. In an example, we will showcase HeartMate 3™, a blood pump with a magnetically levitated rotor and arguably the most complex machine ever implanted into a human being.About the Speaker

The Role of Multiphysics Modeling in Lightning Protection Design and Certification
In the aerospace and wind turbine fields, implementing a suitable lightning protection design is paramount. Lightning, and other electromagnetic effects (precipitation static, radiated fields, etc.), can seriously degrade performance, damage, or even destroy objects without an acceptable protection design. In the past, to determine the threat that lightning poses, several iterations of engineering testing were required to obtain data, which drives the protection features an object must have to survive. This is a high-risk path and can result in tremendous program costs and setbacks. Multiphysics modeling allows for the effects of lightning to be understood without having to perform dozens of test iterations and frequently results in large time and cost savings for programs that use it. In this talk, the role of multiphysics in the development of lightning protection designs and the certification of these designs is discussed as well as the benefits of this approach.About the Speaker

Simulation-Based Approach to STEM Challenges
A new pedagogical approach to STEM challenges is currently implemented in the mechanical engineering program at the University of Hartford. This approach combines problem- and inquiry-based learning, simulations and apps with the COMSOL Multiphysics® software, and emphasizes the importance of outside-of-class learning supported by effective reference materials and faculty mentoring.
A two-course sequence was modified to contain scaffolded and contextualized simulations with application building that develop technical competency in modeling, a deeper understanding of thermofluids concepts by solving realistic technological problems, and writing skills by generating technical reports for each simulation. Apps involve creating a simplified interface that contains the full efficacy of the underlying model but not exposing the end user to its complexity.About the Speaker
Ivana Milanovic is a professor of mechanical engineering at the University of Hartford. She is a contributing author for more than 90 journal articles, NASA reports, conference papers, and software releases. Dr. Milanovic is a member of the Connecticut Academy of Science and Engineering, a body of scientists and engineers that provides support and insight to state agencies and legislature. She received her PhD in mechanical engineering from the Tandon School of Engineering, New York University, and MS and BS from the University of Belgrade, Serbia.
COMSOL® Used as Core Technology for Development of RF/Microwave and High-Speed Digital Connectors
Signal Microwave designs and builds coaxial connectors for microwave and high-speed digital applications. This includes wireless systems, radar, 5G, optical systems, test equipment, back planes, etc. The COMSOL® software is one of our core technologies and is used to design virtually every product we make. This presentation will show how COMSOL Multiphysics® is integrated into our design process and allows us to develop excellent products with a faster design cycle time. A pair of examples will be given, showing how COMSOL Multiphysics® allowed us to minimize the development time, troubleshoot machined material, and meet our customers’ requirements.About the Speaker
Eric Gebhard received his BS in engineering from Arizona State University in 1995. He has worked for over 20 years in various engineering and management positions in both the aerospace and RF industries, with the last 10 years working on RF connector designs and RF simulation using the COMSOL Multiphysics® software. Currently, he is the vice president of Signal Microwave.
Use of the COMSOL Server™ License to Simulate Next-Generation Synchrotron Light Sources
Next-generation synchrotron light sources are creating orders-of-magnitude brighter X-rays by reducing horizontal emittance. This requires the bending magnet pole tips to be closer to the electron beam axis, which in turn requires smaller vacuum chambers. The resultant design challenges are dictated by complex and coupled physical phenomena, including high thermal stresses, photon-stimulated desorption, and electromagnetic wakefields. The Application Builder in the COMSOL Multiphysics® software enables the creation of browser-based graphical user interfaces (GUIs), which enable scientists and engineers to study this complicated problem domain without becoming an expert user of the COMSOL® software. With a relatively inexpensive COMSOL Server™ product license, these GUIs can be run on a cloud-based server, with many processors and all of the required RAM for complex simulations. This approach extends the power of COMSOL Multiphysics® to collaborators, customers, students, etc. We present two such GUIs: 1) the emission of synchrotron radiation and resultant thermal stress on vacuum chamber walls that are downstream of dipole bending sections, and 2) accurate thermal analysis and optimized mechanical bending correction for high-heat-load beamline mirrors. The various challenges of creating the underlying FEA models and the methods used to overcome them will be discussed. Both examples are relevant to the Advanced Photon Source upgrade (APS-U) under construction at Argonne National Laboratory.About the Speaker
Nicholas Goldring is an assistant research scientist at RadiaSoft LLC in Boulder, CO. He has active research interests in X-ray science and accelerator physics. Before joining RadiaSoft, Nicholas was a graduate student member of the multidisciplinary team at Argonne National Laboratory (ANL) tasked with upgrading the Advanced Photon Source (APS) Synchrotron Facility. During his time at ANL, he did significant work on the design and optimization of high-heat-load beamline optics. His familiarity with particle accelerator codes and FEA expertise allow him to continue research and development in the field of modern accelerator design. His current work includes the simulation of complex vacuum chamber systems and the development of user-friendly graphical user interfaces for the benefit of next-generation particle accelerators. Nicholas received his MS in physics from the Illinois Institute of Technology in 2017.
