Product Overview

HFSS™ utilizes a 3D full-wave Finite Element Method (FEM) to compute the electrical behavior of high-frequency and high-speed components. With HFSS, engineers can extract parasitic parameters (S, Y, Z), visualize 3D electromagnetic fields (near- and far-field), and generate Full-Wave SPICE™ models to effectively evaluate signal quality, including transmission path losses, reflection loss due to impedance mismatches, parasitic coupling, and radiation.

HFSS delivers fast simulation speed and the ability to solve large scale simulations:

• Improved meshing - A new highly robust meshing technique that results in efficient, high-quality mesh generation that translates directly to reduced memory and simulation time.
• New element technologies for greater speed and capacity
  • Curvilinear elements - State of the art element technology that increases the fidelity of solutions for curved geometries by providing a precise representation of the electromagnetic fields on "true" surfaces.
  • Mixed element orders - Built upon and leveraging hierarchical basis functions, HFSS automatically and judiciously applies the appropriate element order based on geometry and electromagnetic requirements.
• Adjoint derivatives, a new feature in the Optimetrics™ add-on module, provides direct calculation of S-parameter derivatives with respect to variations in geometry, materials and boundary conditions. This delivers insight into design sensitivity and the effect of manufacturing tolerances. The derivative information accelerates the SNLP optimizer in Optimetrics.
• HFSS-IE option - HFSS-IE is a new solver option that efficiently solves large, open, radiating or scattering problems such as:
  • Antenna placement
  • Radar cross section (RCS)
• HFSS HPC option - Enables new solver technology via Ansoft's breakthrough implementation of the domain decomposition method. With the HPC option, large-scale simulations can be solved across a network of machines using all of their available memory.

HFSS is dynamically linked with Ansoft Designer® to create a powerful electromagnetic-based design flow. This design flow enables users to combine complex, highly nonlinear circuits with transistor-level detail and 3D full-wave accurate component models to solve challenging high-performance electronic designs.
