COMSOL Day: Version 6.2

See what is possible with multiphysics modeling

The release of COMSOL Multiphysics® version 6.2 brings enhanced modeling capabilities, faster solver technology, and improved user experience. It also features game-changing functionality for simulation apps and digital twins. Simulations of electric machinery with nonlinear materials are now faster by an order of magnitude or more, as are impulse response simulations for acoustics.

Computational fluid dynamics (CFD) models now solve up to 40% faster. In chemical engineering applications, the new version includes functionality for simulation of vapor–liquid interfaces, including those in both condensation and vaporization processes. Structural mechanics users will get updated damage and fracture modeling capabilities alongside tools for circuit board warping computation and magnetostructural multiphysics analysis of electric motors.

Join us for this COMSOL Day, where we will introduce you to COMSOL Multiphysics® version 6.2.

The Application Builder and Model Manager provide a way to easily develop and maintain simulation apps and organize models and apps, respectively. Using these workspaces, a large community of engineers can benefit from multiphysics modeling and simulation and collaborate more effectively.

As of version 6.2, there is a feature for Timer events in the Application Builder, which allow for the creation of simulation apps with automated updates. The ability to use both surrogate models and Timer events in simulation apps makes it possible to have standalone apps operate as effective digital twins.

The Model Manager server can now show models and auxiliary files directly in the web interface, which greatly expands the tools applicability. In the Model Manager, maintenance operations have been extended through functionality for deleting versions and purging computed data. A new Model Manager application programming interface (API) can be used to communicate with Model Manager databases.

Join us in this session to learn more about the latest updates in the Application Builder and the Model Manager.

Parallel Session
Surrogate Models, Uncertainty Quantification (UQ), & Optimization

Join this session to learn about the new simulation-data-driven surrogate models in COMSOL Multiphysics®. We will show how this technology can be used to increase the computational speed of an app, leading to a more interactive user experience and promoting wider use of simulations within an organization.

COMSOL Multiphysics® is an ideal environment for generating physics-based training data for data-driven surrogate models. You will learn how to produce such data by using efficient design-of-experiments methods. We will also discuss the role of surrogate model technology in uncertainty quantification and optimization. To conclude, we will highlight the latest additions to the Uncertainty Quantification Module and the Optimization Module.

Acoustics & Structural Mechanics

In this session, we will cover the updates for structural mechanics and acoustics in version 6.2.

Users of the structural mechanics products will see updated damage and fracture modeling capabilities, along with tools for circuit board warpage computation and magnetic–structure multiphysics analysis of electric motors. This version also introduces capabilities for studying transport in solids, which can be used for modeling electromigration and other phenomena. Moisture transport is now more tightly integrated with structural deformations, including how it modifies the storage coefficients and porosity. Inertia relief analysis — now automated in the new version — makes it easier to analyze unconstrained structures that are accelerated by external loads.

This version also introduces a viscoplastic material model specialized for the unique properties of lithium in battery applications. Usability and performance have been significantly enhanced for parameter estimation of experimental data, including uniaxial, biaxial, and cyclic load cases.

For Acoustics Module users, frequency-dependent impedance boundary conditions now enable audio engineers to more accurately simulate acoustics in the time domain with realistic absorption. The Poroelastic Waves feature has been extended to include anisotropic materials, and users will notice considerable performance enhancements in impulse response calculations for room and cabin acoustics simulations using ray acoustics.

Parallel Session
Visualization, Geometry, & Meshing

In this session, we will introduce what's new in visualization, geometry, and meshing in the latest version of COMSOL Multiphysics®.

In version 6.2, enhanced visualization tools now provide functionality for floor shadows, streamlines on curved surfaces, and using contour and isosurface series plots to visualize field progression over time. For geometry modeling, new measurement parameters aid in downstream geometry construction and elsewhere in the Model Builder, making it easier to parameterize models and simplifying the workflow when building simulation apps.

In meshing news, automatic swept meshing can now handle more complex geometries, enabling hexahedron and prism elements without any manual partitioning of linking faces. Additional meshing updates include improvements for creating periodic meshes and remeshing of imported STL file surfaces.

Join us in this session to learn more.

Fluid Flow & Heat Transfer

COMSOL Multiphysics® version 6.2 comes packed with new functionality for fluid flow and heat transfer.

In the CFD Module, large eddy simulation (LES) is implemented for compressible flow for accurate modeling of the flow of gases at Mach numbers below 0.3. There are also seven new Reynolds-averaged Navier–Stokes (RANS) turbulence model interfaces for high-Mach-number flow. A new potential flow interface can be used to get good initial values for the flow and to obtain faster convergence.

In the Heat Transfer Module, the SST turbulence model has been added for accurate nonisothermal flow and conjugate heat transfer simulations. The ASHRAE weather data feature is extended with a search function based on a GPS position, i.e., the feature finds the closest weather station to the GPS position. Additionally, a new thermal connection feature has been added in order to connect and add thermal resistance between two surfaces that are not geometrically in contact in the model.

Join us in this session to learn more about these updates as well as additional fluid flow and heat transfer news!

Parallel Session

In this session, we will cover the updates in the electromagnetics products.

In version 6.2 of the AC/DC Module, nonlinear motor and transformer simulations have become significantly faster due to a new method for time-dimension periodicity. The module now includes dielectric models for tissue simulation, and dedicated functionality streamlines the modeling of imperfectly stranded conductors, like litz wires. For RF Module and Wave Optics Module users, high-frequency analysis, based on the boundary element method, is enhanced by the introduction of new boundary conditions. The Plasma Module offers more efficient handling of chemical reactions in plasmas and microwave plasma simulations. The Semiconductor Module includes several performance and robustness improvements, enabling users to preview doping profiles before solving.

Chemical & Electrochemical Engineering

COMSOL Multiphysics® version 6.2 extends the capabilities for chemical and electrochemical engineering. The Chemical Reaction Engineering Module now supports gas–liquid equilibrium modeling for multiphase flows. Furthermore, the add-on products for electrochemistry and corrosion now include contact resistance on boundaries, eliminating the need to add thin domains in order to model poorly conducting layers. In the Corrosion Module, the ability to define models for cathodic protection of pipelines has been extended with, for example, features to connect edges to external anodes through an external resistance. The Fuel Cell & Electrolyzer Module introduces a pore–wall interaction (Knudsen diffusion) model, enhancing gas diffusion electrode accuracy. Battery modeling is simplified with automatic state-of-charge and state-of-health variable definitions. Additionally, the functionality for specifying the initial charge distribution has been improved, e.g., for the initial state of charge, cell voltage, and electrode voltages.

Join us in this session to learn more about the new functionality for chemical and electrochemical engineering in COMSOL Multiphysics® version 6.2. You will also see a demo of the new tutorial models in these areas.
