- Panel Discussion: Multiphysics Simulation for Product Development
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.

- Sponsored Workshop by SmartUQ - Coupling SmartUQ’s Predictive Analytics and Uncertainty Quantification Solutions with COMSOL®
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.

- Panel Discussion: The Creation and Application of Simulation Apps
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.

- Sponsored Workshop by XPS - High-Temperature Reactors Modeling: From Extractive Metallurgy to Structural Mechanics to Thermodynamic and Multiphysics Coupling
In this workshop, XPS Expert Process Solutions will demonstrate how COMSOL Multiphysics® can be used to simulate high-temperature reactor models. Our experience in the mining, extractive metallurgy, and materials technology areas has given us the opportunity to model several high-temperature industrial vessels using a wide variety of physics involving fluid flow, heat transfer, structural mechanics, reactive flow and chemical kinetics, electric currents, particle tracing, and more. We have also developed a custom thermodynamic chemical equilibrium interface, M4D-CCI, to couple multiphysics simulations to ChemApp™ (or FactSage™) from GTT-Technologies. We will do a live demo of the thermodynamic interface during the workshop and all the attendants will receive a free evaluation version of the thermodynamic interface. To finalize, we will examine four project cases:
- Simulation of slag flow inside a twin DC arc furnace: Understanding how slag or liquid metal flows inside an industrial electric furnace can be used to optimize the integrity of the furnace. 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.
