HP's acquisition was driven by HP's need for an optimization capability for HFSS. (OSA), a company John Bandler founded in 1983. In 1997 Hewlett-Packard acquired Optimization Systems Associates Inc. It was also bundled into Ansoft products. Īnsoft originally sold HFSS as a stand-alone product under an agreement with Hewlett-Packard. He served as its chairman and chief technology officer until 2008, when Ansys acquired Ansoft. Cendes founded Ansoft Corporation to design and develop high performance EDA software.
It was the first general purpose software product to solve arbitrary 3D EM field problems, including EM energy distribution and S parameters in complex structures. HFSS was originally developed by Professor Zoltan Cendes, Ph.D., and his students at Carnegie Mellon University. HFSS is one of several commercial tools used for antenna design, and the design of complex radio frequency electronic circuit elements including filters, transmission lines, and packaging. HFSS captures and simulates objects in 3D, accounting for materials composition and shapes/geometries of each object. The benefits of simulating a circuit's high frequency behavior with high accuracy on a computer reduces the final testing and verification effort of the system as well as mitigating the necessity of building costly multiple prototypes, saving both time and money in product development. ANSYS HFSS allows system and circuit designers to simulate EM issues such as losses due to attenuation, coupling, radiation and reflection. The solver has also been used to simulate the electromagnetic behavior of objects such as automobiles and aircraft. Įngineers use Ansys HFSS primarily to design and simulate high-speed, high-frequency electronics in radar systems, communication systems, satellites, ADAS, microchips, printed circuit boards, IoT products, and other digital devices and RF devices.
Each solver in ANSYS HFSS is an automated solution processor for which the user dictates the geometry, properties of the material and the required range of solution frequencies. Examples of estimated bandwidth of different antennas according to the schedule VSWR and return loss by the help of the ANSYS HFSS Īnsys HFSS (high-frequency structure simulator), is a commercial finite element method solver for electromagnetic (EM) structures from Ansys that offers multiple state-of-the-art solver technologies.
