What does HFSS mean in UNCLASSIFIED

HFSS stands for High Frequency Structure Simulator. It is a 3D electromagnetic (EM) simulation software developed by Ansys that allows users to design, simulate, and analyze the performance of high-frequency structures like antennas, RF filters, and integrated circuits.

With HFSS, engineers of all disciplines can quickly model complex antenna designs and study their behavior with EM field simulations. They can also use the software to virtualize physical devices in various ways — from small components to complete systems — while accounting for factors such as temperature distribution or material properties.

Some of the main features of HFSS include its full wave solving capabilities for analyzing frequency response; finite element technology for analyzing scattering parameters; multi-physics solvers including thermal analysis; full integration with other third party tools; fast solution times via hybridization technology; visualization tools; automated optimization tools; modeling support for single layer substrates; contact synthesis technology for PCB traces and vias; advanced meshing algorithms including local mesh refinement technology; multiple solution engines for greater cross-platform accuracy open APIs for customizing applications and creating custom workflows.

Anyone who needs to design or analyze high-frequency structures such as antennas, filters or integrated circuits will find value in using HFSS. This includes electrical engineers working on wireless communication projects as well as mechanical engineers designing physical objects which interact with electromagnetic radiation or behave in an electromagnetically reactive environment.

The cost of using HFSS depends on a variety of factors such as the type of license you need (e.g., 1 year vs 5 year expiration), number of cores/nodes used per job etc. Generally speaking prices start from around k per year but may be higher depending on your requirements.
