Ansoft Software -

High Frequency Structure Simulator (HFSS) is Ansoft’s flagship product. Its architecture relies on the Finite Element Method. The software does not analyze the geometry as a whole; instead, it performs —discretizing the 3D volume into thousands of tetrahedral elements.

This paper provides a comprehensive technical analysis of Ansoft Corporation’s software suite, a foundational pillar in the field of Computer-Aided Engineering (CAE) and Electronic Design Automation (EDA). Before its acquisition by ANSYS, Inc., Ansoft revolutionized the simulation landscape by introducing the concept of "Physical Design" to high-frequency and high-speed electronics. This treatise explores the theoretical underpinnings of the Ansoft solver architecture—specifically the Finite Element Method (FEM) and Method of Moments (MoM)—and examines how products like HFSS, Maxwell, and Siwave redefined signal integrity, power integrity, and electromechanical design. We argue that Ansoft’s legacy is not merely a collection of tools, but the standardization of electromagnetic field physics within the digital design flow. : Specifically designed for Signal Integrity (SI) and

For electromechanical devices (motors, actuators, transformers), Ansoft’s Maxwell solver employs FEM tailored for low-frequency regimes. Here, the displacement current is often negligible compared to conduction current. This treatise explores the theoretical underpinnings of the
