New Features in COMSOL Multiphysics Version 6.3

In November 2024, COMSOL announced the release of COMSOL Multiphysics® version 6.3. This latest iteration brings a host of innovative features designed to enhance physics modeling efficiency and streamline the development of simulation apps. Let’s dive into what’s new in this powerful simulation software.

Register for this webinar to learn more about version 6.3

New Electric Discharge Module

One of the standout features in version 6.3 is the introduction of the Electric Discharge Module, which equips users with advanced simulation capabilities to tackle a variety of electric discharge scenarios. 

Whether modeling atmospheric pressure gas discharges or breakdown phenomena in liquids and solids, this new module caters to diverse applications—from consumer electronics to high-voltage systems.

COMSOL Technical Product Manager Lipeng Liu reports, “The Electric Discharge Module makes new modeling capabilities available that aid in the design of anything from consumer electronics to high-voltage systems.” It reflects COMSOL’s commitment to providing robust tools for tackling complex multiphysics challenges.

GPU-accelerated simulations

Version 6.3 introduces GPU support that significantly boosts simulation speed—up to 25 times faster for transient acoustics simulations. Available in the Acoustics Module, this feature is crucial for engineers involved in automotive sound systems or who optimize acoustics in building environments.

A development manager at COMSOL, Mads J. Herring Jensen emphasizes, “Being able to produce acoustics simulations much faster will help our users to ultimately develop new design iterations and product innovations more quickly as well.” Clearly, it’s an improvement that not only enhances simulation productivity, but also facilitates faster iterations and design refinements.

Streamlined model development

New automated geometry preparation tools within COMSOL are designed to simplify and accelerate model development. These tools automatically remove unnecessary details and defects from CAD models, which makes for higher-quality meshes. Users can now import larger industrial CAD models that may not have been originally intended for simulation and transform them for reliable analysis.

Additionally, the introduction of an interactive Java environment allows for on-the-fly model modifications through the COMSOL API. A new chatbot tool is included to assist with Java coding and general inquiries, so that users receive effective support during their modeling process.

Enhanced features throughout the product suite

Other notable highlights of COMSOL Multiphysics® version 6.3 include:

• Efficient data sampling for surrogate model creation;
• Improvements in electromechanical modeling for thin structures;
• Tools that accommodate moisture-induced swelling and simplified workflows for spot welds;
• Enhanced electrostatic force calculations for MEMS devices;
• Better modeling of laminated iron in motors and transformers; and
• Incorporation of Reynolds-stress turbulence models and non-Newtonian flow simulations.

These enhancements contribute to more accurate and versatile simulations across various domains, including fluid dynamics, heat transfer, and chemical applications.
