HFSS Leads the Way with Exponential Innovation

As engineers continue to design more complex systems with increasing frequency, the need for speed and capacity to solve these structures also increases. Over the years, HFSS has come a very long way and can now solve exponentially large structures with millions of unknowns. Ansys HFSS never stopped advancing,  continuing to innovate to meet the demands of electromagnetic analysis in modern electronics.

The exponential evolution of HFSS has proven its growth and capability of solving the most complex structures. In 1990 it could solve a matrix size of merely 10,000 and is now capable of solving the largest and most complex structures with over 800 million unknowns in 2022, and we look forward to soon crossing the next major milestone.

This is an extraordinary achievement because it demonstrates the remarkable progress that has been made in computational electromagnetics. Just a few decades ago, simulating designs with a matrix size of a few thousand was considered revolutionary, but today we can simulate designs approaching a of 1 billion. This is a testament to the power of HFSS and the ingenuity of its users.

HFSS: From micron to meter scale

HFSS can solve anything from chips to ships and satellites. One reason HFSS can handle such large and complex designs is Mesh Fusion. Meshing is the process of dividing a complex geometry into smaller, simpler parts inside which equations of physics are established and collectively generate a large matrix to solve. This matrix solution returns the electromagnetic fields and the SYZ parameters. The most complex systems consist of multiple geometries like PCBs, cables, connectors, and inside platforms such as aircraft or automobiles and each type of geometry can benefit from a different meshing strategy. To solve these challenges Ansys introduced Mesh Fusion technology.

Mesh Fusion creates multiscale system meshes of high quality quickly and easily, reducing the amount of time required to generate meshes for complex geometries that are more efficient and accurate for their specific analysis needs. Mesh Fusion works by creating a virtual topology that defines how different meshes are blended together. This patented approach is particularly useful for complex geometries where it may be difficult or time-consuming to create a single mesh that conforms to all the features of the geometry.

This video illustrates the capacity and level of complexity that HFSS can handle easily. It solves the electromagnetic behavior of the entire system with the highest accuracy and speed from micron to meter scale.

In this video, you can see how HFSS solved the chip behavior in context of the IC package, mobile behavior in context of the automobile “system”, and further the automobile activity in context of its EMI/EMC testing environment. Whether it’s the tiniest chip in the mobile device or the car or the environment, HFSS can solve the most complex systems conceivably. Advanced packaging also introduces new challenges like signal integrity, power delivery, and thermal management. With HFSS plus Ansys multiphysics technology such as Icepak, engineers can succeed at delivering the most cutting-edge products possible.

The Mesh Fusion technique and the capacity to solve without sacrificing accuracy, continue HFSS’s long-standing role as the engineers’ electromagnetic tool of choice, the true “Gold Standard”. The High-Tech industry is rapidly adopting 5G/6G technology and HFSS plays a key role in designing and optimizing these next-generation wireless networks. In the above video, you can easily relate how HFSS is simulating the electromagnetic behavior of mobile in the context of cars.

As everyday items, like cars, become computers on wheels, and begin requiring more sophisticated electronics, they are creating a challenge for electromagnetic compatibility (EMC). With HFSS, automotive manufacturers can simulate the entire vehicle, including the wiring harnesses, sensors, and electronic devices within it, to ensure compliance with EMC regulations and prevent electromagnetic interference. Further, they can simulate the entire car in the context of the car’s environment, such as a city, and nearby cellular towers.

It is not surprising that virtually all the world’s most advanced and powerful electronics are designed using HFSS. This is a remarkable achievement and a testament to the power of HFSS, the technology is pervasive. Whether it’s designing advanced radar systems, ensuring EMC compliance in cars, or optimizing next-generation wireless networks, Ansys HFSS is the key to success.
