Multipurpose, full wave 3D electromagnetic (EM) simulation software for designing and simulating high-frequency electronic products such as antennas, components, interconnects, connectors, ICs and PCBs.
Ansys HFSS is industry‑trusted full‑wave 3D electromagnetic software used to validate and sign off complex electronic designs. Engineers rely on HFSS to analyze antennas, RF and microwave components, IC packages, PCBs, and full systems—leveraging connected, multiphysics workflows that enable system‑aware design from silicon through final system verification.
HFSS enables early electromagnetic insight and rigorous validation across antennas, RF, SI/PI, and EMI/EMC—helping engineers explore design tradeoffs sooner, reduce rework, eliminate uncertainty, and confidently validate fully coupled electronic systems from initial concept through final signoff.
How Ansys HFSS Mesh Fusion solves much larger designs than ever thought possible
HFSS Mesh Fusion’s patented technology enables much more complex designs to be simulated with the same rigor, accuracy and reliability of Ansys HFSS. It accomplishes this by applying targeted meshing technologies within the same design, appropriate to the local geometry.
HFSS Mesh Fusion continues to use the same “electromagnetically aware” adaptive meshing technology as before without compromising accuracy because a fully coupled electromagnetic matrix is solved with each adaptive mesh step and for each point in a frequency sweep.
“After a two-year extensive evaluation against multiple industry products…we found HFSS is truly the 'golden standard' in electromagnetic modeling... HFSS produced extremely accurate results with no discernible difference between measured and modeled results.”
“Ansys HFSS Mesh Fusion makes it possible… to create optimal designs, shrink design cycles and cost… Leveraging Mesh Fusion, we are innovating highly advanced designs that were previously unimaginable…we simulated the EM transmission of an entire room.”
“Ansys HFSS can solve any structure, regardless of complexity, enabling creative out-of-the-box designs…Because with HFSS in the loop, we go into the lab to confirm results, not discover them.”
“Our goal is always to propose and deliver high-quality, high-performance connectors to our customers in a timely manner. Ansys HFSS software has become an indispensable tool for improving the design quality and rapid release of high-speed transmission connectors.”
“We went with Ansys …because of the exquisite accuracy. My philosophy is to take the time to design it right the first time so that you don’t have to build it multiple times…The simulated world that Ansys enables is crucial to Samtec’s R&D”
