Ansys HFSS (high-frequency structure simulator)  is a commercial finite element method solver for electromagnetic (EM) structures from Ansys.

Engineers 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. The solver has also been used to simulate the electromagnetic behavior of objects such as automobiles and aircraft. ANSYS HFSS allows system and circuit designers to simulate EM issues such as losses due to attenuation, coupling, radiation and reflection.

The benefits of simulating a circuit's high frequency behavior with high accuracy on a computer reduce the final testing and verification effort of the system as well as mitigating the necessity of building multiple costly prototypes, saving both time and money in product development.
