MODELING & SIMULATION | COMSOL FEATURE Simulation results showing the sound pressure distribution generated by a loudspeaker driver. Image made using Comsol Multiphysics software. The new multiphysics modules help GM's engineers visualize the temperature profile in liquid-cooled Li-ion battery packs. "When we want to put the battery pack together with inverters and other components, a 1D model gives us the quickest results," Garrick said. "If we're trying to work out some aspects of battery pack design, 3D models give us the best results. 3D has the highest fidelity." Comsol also unveiled a compiler program that makes it easier to share apps. It even lets users who don't have the company's software view models and simulations. Version 5.4 attempts to balance the need to provide more ways to analyze the subtleties of each design with the need to offer tools that don't take a long time to learn. Modules dedicated to specific fields are among the company's ease-of-use techniques. That approach also helps specialists in these fields delve into the subtle factors that determine end performance. "We have more modules for specific applications," noted Valerio Marra, the company's marketing director. "They make it easier to do the work in those fields, since many advanced factors are tailored to the application."
