North America Schedule

October 7-8, 2020 | 10 a.m. EDT (UTC-4)

10:00 a.m.
  • Welcome to the COMSOL Conference
  • Poster, Paper, and Exhibit Hall Opens
10:10 a.m.
Panel Discussion
  • The use of simulation for product and process development has come a long way from its origins, when experts programmed their own algorithms. Product development has, since then, been augmented by the use of simulation software that originally modeled single-physics applications and more recently models phenomena described by multiphysics simulations.

    This panel includes skilled and proficient COMSOL Multiphysics® users who will discuss this topic by drawing upon their wide-ranging experiences and applicable examples. With panelists from the automotive, biomedical, and consumer product industries, you will hear how multiphysics simulation allowed them to understand their designs and processes better, conceptualize and optimize these designs, and bring products to market quicker and with higher quality than before.

    The panelists will also discuss new trends in the simulation software industry, such as the democratization of simulation and the use of HPC. Questions will be taken from the audience, and we envision an exciting and fulfilling discussion.

  • Advancements in and the rapid proliferation of modeling and simulation have led to new technologies, such as digital twins, and given engineers a “data-rich” environment for conducting predictive analytics. Yet simulations are a deterministic analysis, failing to consider real-world variability and uncertainties surrounding the simulation process. By accounting for the uncertainties in their simulation models, engineers can develop an accurate predictive model, enabling the performance of advanced analytics, including uncertainty quantification (UQ), design space exploration, trade studies, and predictive maintenance. These predictive capabilities can significantly reduce product development, warranty, and sustainment costs and improve product reliability and durability.

    Using SmartUQ’s integration with COMSOL® for illustration, this workshop will show how SmartUQ software can enhance product development and design exploration activities in COMSOL® through the application of predictive analytics and UQ techniques. Using NACA airfoil CFD and microwave ablation simulations for demonstration, this workshop will walk through SmartUQ’s analytics workflow coupled to COMSOL Multiphysics®. The workshop will also highlight additional applications of SmartUQ to other COMSOL® simulations.

  • There are many different energy-based medical devices, with applications covering RF ablation, cancer therapy, cosmetic surgery, defibrillation, and electrosurgery. The power supply requirements for such devices can vary significantly, as some devices require operating at RF frequencies as opposed to DC, pulsed instead of continuous, or using custom waveforms to prevent neurostimulation or charge accumulation. Power supply development must be tightly integrated with the probe design, which ultimately delivers the energy to the targeted area. This workshop gives an overview of how to use COMSOL Multiphysics® to design an energy-based medical device, including considerations for both the power supply and the probe.

  • Diagnosing Process Problems Using Multiphysics and Multiscale Simulation

    Simulation is often used in Saint-Gobain to diagnose problems we are having with products or processes. Compared to other FEA or CFD software, COMSOL Multiphysics® is helpful for problems that are multiphysics and multiscale.

A generalized example related to reactions in porous media in industrial reactors will be shown in this talk. The example can be related to drying, sintering, debinding, purifying, vapor deposition, and similar processes.

  • To reach the highest level of realism, the simulation of processes and devices should take into consideration all physical phenomena that affect them. With the computational resources available to the typical engineer, high fidelity and accuracy is expected in technical designs, which cannot be achieved unless multiphysics behavior is accounted for.

    Where do we go from here? Should multiphysics simulation be confined to the physics experts, those proficient in the methods required to model such effects? Should we control and manipulate high-performance hardware used for simulation? As the applicability of modeling and simulation expands dramatically, why doesn't the number of engineers able to partake in this integral part of product development rise as well? COMSOL provides a solution to these questions: simulation apps, tailor-made applications with defined and controlled user interfaces, inputs, and outputs.

    This panel discussion will investigate apps and how they are currently being applied to research and development within government research and industrial application development. In particular, the panelists will recount their experience with the creation of simulation apps from original multiphysics models and, more importantly, why they decided to create apps. The audience will be able to ask their own questions to the panelists and recount their own experiences.

In this model, Lorentz forces due to electric and magnetic fields are calculated as the driving force for slag flow.
    • A multiscale model of a cooling spray chamber for off-gas treatment: In this model, a water spray model was developed to design an off-gas cooling chamber. A multiscale approach was used by first developing a 1D transient model for the evaporation of a single droplet, which was incorporated to a 3D particle tracing model for the spray. Then, the conjugate heat transfer model for the gas phase was coupled to the reactive particle model to estimate the temperature drop inside the chamber.
    • Brick lining stress evaluation: One of the main sources of stress in a bricked lined cylinder is interference between the brick lining and the shell. Brick lining is a specific type of system that transfers compression, but not tensile stress. Kilns generally have a working lining and an insulating lining. This section presents some of the basic considerations for the evaluation of a brick lining design from a mechanical standpoint.
    • Case study for an emergency repair of a SO2 plant blower: The blower is the heart of the sulphuric acid plant. It pulls and pushes the SO2-bearing gases through the different stages of conversion and absorption of SO2 into sulphuric acid. Cracks were found on the impeller and wear was observed on the shaft of the blower, which prompted emergency repairs. This case study looks into the details required to provide an adequate repair plan.

Q&A and Break
3:15 pm
Tech Café, Minicourses, User Presentations, and 1-on-1 Support Sessions
  • In this minicourse, you will learn how to create simulation applications using the Application Builder in the COMSOL Multiphysics® software. A simulation application has a specialized user interface and allows for nonspecialists in modeling to benefit from simulations. This minicourse will also give an overview of the different methods of deployment you can use to spread the use of simulation in your organization and to your customers. You will learn how to create standalone applications using COMSOL Compiler™ as well as how to make simulation applications accessible using COMSOL Server™.

    Speaker: Bjorn Sjodin


  • In this minicourse, you will learn about the news in the latest version of the Ray Optics Module. We will introduce some new ways to release rays and handle ray-boundary interactions, as well as some new material models. We will also share some updated Application Library examples and showcase improvements in image simulation capability.

    Speaker: Stuart Barnes


  • Join this Tech Café to ask questions and participate in discussions surrounding COMSOL's solvers, including stationary, parametric, and time-dependent methods.

    Speaker: Jacob Yström
