Accelerating Development Using COMSOL Server™
The theory, modeling, and simulation teams at Gore develop many mathematical models and simulation tools that play a very important role in guiding new technology development. A major challenge that we face is deploying these tools for broader use across the enterprise, including our research centers in Europe and Asia. In this talk, I will discuss how we address this problem using the COMSOL Server™ product and our experience in using it over the last year. I will also discuss what advantages and limitations we have seen during our use and potential new capabilities that would enhance user experience.About the Speaker

Designing Durable Audio Transducers
Audio transducers are the devices in loudspeakers that convert electrical signals into outgoing pressure waves, allowing the consumer to enjoy music. Finite element analysis is commonly used to enable design optimization for such devices to hit their performance targets. A topic less often investigated in the industry is the one of durability: how to design devices such that they can withstand the rigors of operation, handling, and their environment. This presentation outlines some design practices involved with designing transducers for durability in a predictive manner and discusses some of the ongoing challenges in such efforts.About the Speaker

Beyond Modeling and Simulation in the Biopharma Industry
The Digital Integration and Predictive Technologies (DIPT) team at Amgen is tasked with transforming the way that Amgen does process development through the development, application, and deployment of mechanistic models and other digital/predictive technologies. These efforts span the life cycle of molecules and products (from prepivotal to commercial stages) across all functions within process development and beyond (including drug substances/products and devices as well as engineering and manufacturing). In order to achieve this goal, DIPT develops models based on a multiphysics paradigm and implements/deploys a subset of these models in the COMSOL® software. In this talk, we will describe a half a dozen applications involving various transport phenomena; chemical reactions; and other physicochemical processes, including chromatography separations and device sterilizations, among others. The examples will go beyond conventional simulations and parameter sweeps and demonstrate the use of mechanistic models in uncertainty/risk-based analyses. Model deployment considerations will be discussed, given Amgen's leading vision in this front.About the Speaker
Pablo Rolandi (PhD) leads the Advanced Modeling and Simulation Team within the Digital Integration and Predictive Technologies Group, where he is responsible for the modeling strategy and portfolio across process development. His interests span in silico mechanistic models for process simulation, synthesis (design), and optimization; with an emphasis on inverse problems, uncertainty, and design/control. Before joining Amgen in 2016, Pablo developed advanced tools and modeling methodologies and consulted for Fortune 500 companies in the space of process modeling.
Using Multiphysics to Diagnose the Cause of a Toxic Leak
A safety critical valve failed during testing, exposing workers to a toxic fluid. One potential reason for the leak was thermal damage to the interior polymer gaskets and seals within the valve resulting from the valve’s welding installation. Veryst Engineering used the COMSOL Multiphysics® software to simulate the welding process, tracking the evolving weld-induced temperature that could exceed the polymer gaskets’ safe-use temperatures. Our analysis, described in this presentation and supported by testing, provided a thorough understanding of the problem and the most plausible explanation for the release.About the Speaker

He has consulted in metal forming, semisolid materials, powder metallurgy, drawing, forging, welding, cold and hot rolling, electrical contacts, and extrusions. Prior to founding Veryst Engineering, Dr. Brown was director at the Boston office of Exponent, Inc. Before Exponent, he was on the faculty of the Department of Materials Science and Engineering at the Massachusetts Institute of Technology.
Modeling Nuclear Fuel: A Study in Multiphysics
Nuclear fuel experiences a complex environment of elevated temperatures, temperature gradients, mechanical loading, thermal expansion, swelling, densification, radiation, and continuously evolving composition and microstructure. Understanding and predicting the coupled, aggregate behavior is crucial for optimizing the design and operation of the fuel. In this talk, I will present two COMSOL Multiphysics® models developed for modeling the continuum and microstructural aspects of nuclear fuel.About the Speaker
Andrew Prudil completed his PhD and postdoctorate in nuclear engineering at the Royal Military College of Canada, where he developed models of nuclear fuel behavior. Currently, he works at Canadian Nuclear Laboratories in the Fuel & Fuel Channel Safety Branch. He focuses on the development and application of computer models to improve the safety, economics, and sustainability of nuclear energy. Andrew has contributed to commercial, government, and academic R&D projects such as fuel irradiation safety cases. He has also coauthored numerous journal papers, conference papers, and reports. Most recently, he coauthored a textbook on nuclear engineering that is being published later this year.
