COMSOL Day: Automotive

Understanding the coupled physical phenomena at play is crucial when using modeling and simulation for the research and design of vehicle electrification technologies like batteries, high-voltage cables and connectors, electric powertrains, and power electronics. To account for this complexity, scientists and engineers from industry-leading organizations rely on the multiphysics modeling capabilities of the COMSOL Multiphysics^® software.

The software is also widely used for related automotive applications, including loudspeaker design and cabin acoustics. In addition, its unique functionality for creating standalone simulation apps based on multiphysics models and surrogate models makes it possible for larger groups of engineers and scientists within an organization to benefit from modeling and simulation.

Attend this session to get an overview of how multiphysics models, simulation apps, digital twins, and surrogate models are used for vehicle-electrification and related automotive applications. We will also introduce the specific topics that will be covered in each session during this COMSOL Day.

Automotive acoustics play a vital role in the development of advanced car audio systems for precise sound reproduction and the integration of smart system and AI-enhanced functionality. This multidisciplinary field merges acoustics, structural mechanics, and electromagnetics to model and optimize key components essential for vehicle performance and passenger experience.

The COMSOL^® software is well suited for multiphysics and multimethod acoustics modeling for broadband cabin acoustics with integrated audio systems and personal sound zones, electroacoustic speaker design, and vibroacoustic analysis of vehicle structures, including car door stiffness analysis and rattle prediction.

Join this session to learn about the capabilities of COMSOL Multiphysics^® for modeling cabin acoustics.

Modeling and simulation supports battery development by enabling virtual evaluation of battery performance under a wide range of operating conditions. COMSOL Multiphysics^® can be used to model electrochemical processes within battery cells together with the thermal, mechanical, and electrical behavior of battery modules, packs, and surrounding components.

This session will provide an overview of battery modeling workflows in COMSOL Multiphysics^®, addressing topics ranging from electrochemical cell models and aging studies to thermal management and battery pack design. Additional topics will include:

• Charge and discharge simulations
• Thermal and electrochemical coupling
• Battery packs containing hundreds of individually modeled cells
• Surrogate modeling
• Cosimulation for system-level design
• Structural analyses like indentation and penetration tests

As cars and trucks increasingly rely on electrical control units (ECUs), there is a growing need for efficient power electronics devices such as power optimizers, converters, rectifiers, amplifiers, and switches. For electric vehicles, the design of efficient electric powertrains, including inverters and capacitors, is essential for extending battery life and range.

The COMSOL Multiphysics^® software provides specialized functionality for modeling and optimizing these devices. In addition to specialized features for lumped circuit extraction, the software also provides multiphysics modeling capabilities that enable users to include thermal and structural effects when designing semiconductor devices and power modules, including metal–oxide–semiconductor field-effect transistors (MOSFETs) and insulated-gate bipolar transistors (IGBTs).

Join this session to learn more about the capabilities of the COMSOL^® software for modeling components in power electronics. We will provide an overview of how the AC/DC Module and the Semiconductor Module can be used to model and simulate power electronics devices.

The COMSOL Multiphysics^® software provides comprehensive functionality for research, development, and design in vehicle electrification. It offers efficient modeling and simulation capabilities for studying a wide range of physical phenomena, as well as tools for creating standalone simulation apps. The Application Builder and COMSOL Compiler™ make it possible for larger groups of scientists and engineers to benefit from simulations through the use of these standalone apps.

In addition, COMSOL Multiphysics^® includes functionality for creating surrogate models trained on data generated from high-fidelity multiphysics models. These surrogate models can be used to generate synthetic data for training physics-based AI models and, once trained, are compact and computationally efficient, making them well suited for use in simulation apps and digital twins.

In this session, you will learn about the capabilities of the COMSOL^® software for creating simulation apps, surrogate models, and digital twins.
