EM Simulation as Game Changer

Electromagnetic simulation software enables engineers to investigate the electromagnetic properties of components or whole systems efficiently. Electromagnetic (EM) systems pose multiscale challenges, such as very wide frequency ranges and electrically large structures with very fine detail. Dedicated solvers exploit specific numerical technologies for fast and accurate simulation. EM simulation can be applied throughout the entire design process. From the inception of an idea, to the synthesis of components to meet specifications, to analyzing the electromagnetic performance under operational conditions: virtual prototypes are transforming the design cycle.

EM simulation software is a game changer when it comes to reducing the time and cost of bringing a product to market, not just in the high-tech industries of electronics and communication, but also in aerospace, defense, transportation and life sciences. Analysis with EM software ranges from individual components such as antennas, sensors and chips up to entire devices, including aircraft, smartphones and MRI.

Co-design within the SIMULIA product portfolio integrates EM simulation into industry processes, accelerating the process of evaluating the performance, reliability and safety of materials and products before committing to physical prototypes. Multiphysics design flows on the 3DEXPERIENCE platform drive the development process from the earliest stages.
