This introductory demonstration will show you the fundamental workflow of the COMSOL Multiphysics® modeling environment. We will cover all of the key modeling steps, including geometry creation, setting up physics, meshing, solving, and postprocessing.
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.
Acoustic Wave Propagation in 3D Media: Perfectly Matched Layer Formulations
Perfectly matched layers (PMLs) are a well-developed method for simulating wave propagation in unbounded media, enabling the use of a reduced computational domain while avoiding spurious boundary reflections. However, many auxiliary variables are usually needed to describe PML formulations (especially in the time domain) and the problem becomes more complex in the 3D case. Compact formulations are proposed for the time-domain modeling of wave propagation in an unbounded general anisotropic solid and coupled fluid-solid media. The formulations have a second-order form that has the advantages of well-posedness and amenability to being implemented using the finite element method. The COMSOL Multiphysics® software is used for the validation of our formulations. Extension of the PML formulation to model a viscoelastic medium is also provided.

Canadian Nuclear Laboratories 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.
University of Toronto Hisham Assi earned his PhD in electrical engineering and biomedical engineering from the University of Toronto. His thesis was about the time-domain modeling of elastic and acoustic wave propagation in unbounded media, with application to metamaterials. He is currently a postdoctoral researcher in the Ultrasound Lab at the University of Toronto. There, he is extending his wave propagation models to the more general 3D and viscous cases, and his models are being used by collaborators in biomedical imaging. Simultaneously, he is studying photoacoustic imaging as a postdoctoral researcher at Ryerson University through an industry Engage Grant with FUJIFILM VisualSonics. Hisham has coauthored a number of papers, participated in several conferences, and was an invited speaker at the COMSOL Conference 2015.
