Watch the video to learn how HFSS, the gold-standard, full-wave electromagnetic field

solver, will help you solve your most challenging RF, microwave and high-speed designs.


Each HFSS solver incorporates a powerful, automated solution process, so you need only to specify geometry, material properties and the desired output. From there, HFSS automatically generates an appropriate, efficient and accurate mesh for solving the problem using the selected solution technology. With HFSS, the physics defines the mesh; the mesh does not define the physics.HFSS offers multiple state-of the-art solver technologies based on finite element, integral equation or advanced hybrid methods to solve a wide range of microwave, RF and high-speed digital applications. The software includes a linear circuit simulator with integrated Optimetrics for input and matching network design.

Design sign-off accuracy is provided by HFSS through its groundbreaking and industry leading adaptive meshing technology. Its powerful meshing and solver technologies allow you to design with confidence, knowing the results provided by HFSS can be relied on. Other tools simply give answers without any feedback regarding the accuracy of the solution, leading to uncertainty. When combined with Ansys HPC technologies, like domain decomposition or distributed frequencies, HFSS can simulate at a speed and scale never before thought possible, further allowing you to more fully explore and optimize your device’s performance. With HFSS you know your designs will deliver on their product promise.
