What’s new in Simcenter Flux 2026.1
Electromagnetic simulation plays a critical role in the development of electric machines, power electronics and other low-frequency electromagnetic devices. As electromagnetic models become larger and more complex and development cycles continue to shorten, engineers are expected to balance simulation accuracy, workflow efficiency and engineering productivity while supporting an increasingly connected simulation process.
Simcenter Flux 2026.1 introduces new capabilities that help engineers accelerate electromagnetic simulations, simplify model creation and extend electromagnetic workflows across optimization, multiphysics and system-level engineering activities
Accelerate electromagnetic simulations
As electromagnetic models continue to grow in size and complexity, engineers are constantly looking for ways to reduce simulation effort while maintaining accuracy. Simcenter Flux 2026.1 introduces several enhancements that accelerate low-frequency electromagnetic simulations through numerical innovations, while also providing greater flexibility during model preparation and modification.
A major addition in this release is the extension of the Integral Method to transient magnetic simulations. By eliminating the need to mesh large surrounding air regions, engineers can significantly reduce model complexity and simulation effort while maintaining accurate representation of eddy-current and capacitive effects.
