A LESSON IN Multiphysics

OEM engineers reveal how new software from Comsol improved their modeling and analysis of EV battery performance and audio-system sound quality.

Modeling and simulation are becoming a more critical factor in automotive design, particularly in subjective areas like passenger-cabin sound quality and complex newer technologies like battery management. Design tool suppliers are increasing the power of those tools while also making them easier to use.

Tools that handle multiple physics categories are becoming more important as engineers need to understand how complex interactions change when various parameters are adjusted. At the recent Comsol Users Conference, technologists from General Motors and Nissan detailed their efforts to understand nuances in audio systems and electrified-vehicle battery packs.
