Welcome to Ansoft HFSS
HFSS is a high-performance full-wave electromagnetic(EM) field simulator for arbitrary 3D volumetric passive devicemodeling that takes advantage of the familiar Microsoft Windows graphical user interface. It integrates simulation,visualization, solid modeling, and automation in an easy-to-learn environment where solutions to your 3D EM problemsare quickly and accurately obtained. Ansoft HFSS employs the Finite Element Method(FEM), adaptive meshing, andbrilliant graphics to give you unparalleled performance and insight to all of your 3D EM problems. Ansoft HFSS can beused to calculate parameters such as S-Parameters, Resonant Frequency, and Fields. Typical uses include:
Package Modeling
PCB Board Modeling
Silicon/GaAs
EMC/EMI
Antennas/Mobile Communications
Absorption Rate(SAR), Infinite Arrays, Radar Cross Section(RCS), Frequency Selective Surfaces(FSS)
Connectors
Waveguide
Filters
HFSS is an interactive simulation system whose basic mesh element is a tetrahedron. This allows you to solve anyarbitrary 3D geometry, especially those with complex curves and shapes, in a fraction of the time it would take usingother techniques.
The name HFSS stands for High Frequency Structure Simulator. Ansoft pioneered the use of the Finite ElementMethod(FEM) for EM simulation by developing/implementing technologies such as tangential vector finite elements,adaptive meshing, and Adaptive Lanczos-Pade Sweep(ALPS). Today, HFSS continues to lead the industry withinnovations such as Modes-to-Nodes and Full-Wave Spice™.
Ansoft HFSS has evolved over a period of years with input from many users and industries. In industry, Ansoft HFSSis the tool of choice for high-productivity research, development, and virtual prototyping.

Toolbars
The toolbar buttons are shortcuts for frequently used commands. Most of the available toolbars are displayed in thisillustration of the Ansoft HFSS initial screen, but your Ansoft HFSS window probably will not be arranged this way. Youcan customize your toolbar display in a way that is convenient for you.
Some toolbars are always displayed; other toolbars display automatically when you select a document of the relatedtype. For example, when you select a 2D report from the project tree, the 2D report toolbar displays.
Right-click the Ansoft HFSS window frame.
A list of all the toolbars is displayed. The toolbars with a check mark beside them are visible; the toolbars withouta check mark are hidden. Click the toolbar name to turn its display on or off
To make changes to the toolbars, select the menu item
