COMSOL Multiphysics^® version 6.3 delivers new simulation capabilities, significant performance improvements, and user interface enhancements. The new Electric Discharge Module enables detailed simulations of discharges in gases, liquids, and solids while GPU acceleration offers up to 25x faster acoustics simulations and surrogate model training. New geometry preparation tools automatically remove small geometric details for faster and more robust simulations. A new interactive Java environment supports on-the-fly model modifications using the COMSOL API for use with Java, with an optional chatbot tool providing contextual assistance for Java programming.

For structural analysis, multiphysics capabilities have been added for modeling the electromechanics of thin structures and moisture-induced swelling, and new features simplify modeling of spot welds and fasteners. Fluid flow modeling has been extended with Reynolds-stress turbulence models for simulating anisotropic and separated flow patterns.

Electromagnetics simulations now offer more accurate electrostatic force calculations for MEMS devices and new tools for efficient modeling of laminated iron in motors and transformers. A new workflow improves the handling of periodic structures in wave optics, and an RLGC parameter extraction tool enhances transmission line modeling for RF and microwave applications.

Learn more about these updates and other major news in COMSOL Multiphysics^® version 6.3 by attending this session.

In this session, you will learn the fundamental workflow of the Model Builder in COMSOL Multiphysics^®. We will go through all of the steps for setting up a multiphysics model, including the definitions, geometry, materials, physics, mesh, study, and results. You will learn how to set up a multiphysics model that accounts for electric currents, heat transfer, and structural analysis as well as the multiphysics phenomena of Joule heating and thermal expansion.

The AC/DC Module brings new layout tools for motor windings and magnet arrays, extending the functionality for modeling electric motors. This version of the module also introduces a new interface for magnetohydrodynamics that can be used to model flow in molten metals, ferromagnetic fluids, and plasmas subjected to electromagnetic fields. Furthermore, an add-in for electric circuit analysis makes it possible to reduce full finite element models to simple electric circuit representations.

In the RF Module, a new feature for predefined pulses can be used to study electric discharge and lightning strikes. Moreover, there is an important workflow enhancement in the module: a waveguide port mode preview functionality. For users of the Wave Optics Module, there is a new feature that enables the modeling of antireflective coatings and general thin optical layers. Efficient modeling of periodic structures is available in both the Wave Optics Module and RF Module, making it easier to model metamaterials. For users of the Plasma Module, there is a new multiphysics interface for modeling inductively and capacitively coupled plasmas.

In this session, we will discuss the abovementioned updates in greater detail and give you an overview of the additional new features and improvements in the electromagnetics-based modules.

Get an overview of using the CFD Module for laminar, turbulent, non-Newtonian, and multiphase flows as well as flow in microfluidic devices. We will discuss conjugate heat transfer with the combination of heat transfer in solids and heat transfer in fluids, including thermal radiation effects. These phenomena could also be coupled with structural mechanics, chemical reactions, and particle tracing.

Describing and predicting structural mechanics behavior has long been supported by mathematical modeling (often finite-element-based). Yet, modeling acoustics behavior is relatively new in comparison. Both behaviors require a similar approach to modeling, which will be demonstrated in this session using the COMSOL^® software.

Adding the Acoustics Module, Structural Mechanics Module, and other structural mechanics add-on modules to COMSOL Multiphysics^® provides access to modeling and simulation functionality that is useful for analyzing structural mechanics and acoustics phenomena. The built-in features in these modules enable you to model and couple physics phenomena such as thermal stresses, fluid–structure interaction, piezoelectricity, poroelasticity, electromechanics, ultrasound devices, microacoustics, loudspeakers, aeroacoustics, and flow-induced noise. For acoustics specifically, you can model applications based on pressure acoustics, sound quality and noise reduction performance, and acoustics for large or small rooms.

In this session, we will provide an overview of the modeling capabilities of the Structural Mechanics Module and Acoustics Module through examples and demonstrations.

This session will cover news in the Chemical Reaction Engineering, Electrochemistry, Electrodeposition, Corrosion, Battery Design, and Fuel Cell & Electrolyzer modules.

Highlights include:

• New and improved features for porous reactor modeling in the Chemical Species Transport interfaces
• Modeling species adsorption and desorption on electrode surfaces
• The new Cathodic Protection interface for modeling corrosion protection
• New intercalation strain functionality for battery electrode modeling
• Electroosmotic water drag and membrane crossover in fuel cells and electrolyzers

Physics-based simulation apps can be customized for specific needs and leveraged to democratize the use of advanced simulation tools among an expanded community of engineers and scientists. Using COMSOL Compiler™, you can transform these simulation apps into standalone executable files that can be widely distributed and run without license restrictions. This functionality enables a broader application of simulation technology across different departments and teams, facilitating interactive, real-time decision-making based on accurate simulation results.

In this session, we will demonstrate how simulation apps, powered by COMSOL Compiler™, can extend the reach of simulation and enhance collaboration between departments and business units. You will learn how to create and deploy compiled simulation apps, which serve as powerful tools for both expert users and those with no simulation experience.

Simulation results enable users to evaluate fields and variables and visualize them in ways that might be difficult to do with experiments. The COMSOL Multiphysics^® software includes unique functionality for interpreting mathematical expressions of variables, derived variables, functions, and parameters, which can be used on the fly to evaluate and visualize results. You can plot any function of the solution variables and their derivatives using surface, isosurface, slice, streamline, and many more plot types by simply typing in the mathematical expression or selecting variables from a list. The software also provides functionality for visualizing material appearance, lighting, environment reflections, and shadows — which, when combined with plots, create impressive images that can highlight important concepts of a design or process. Join us in this session to learn how to calculate derived values, create stunning plots, and generate reports and presentations using COMSOL Multiphysics^®.
