ANSYS HFSS software is the industry-standard simulation tool for 3-D full-wave electromagnetic field simulation and is essential for the design of high-frequency and high-speed component design. HFSS offers multiple state-of the-art solver technologies based on either the proven finite element method or the well established integral equation method. You can select the appropriate solver for the type of simulation you are performing.
Engineers rely on the accuracy, capacity, and performance of HFSS to design high-speed components including on-chip embedded passives, IC packages, PCB interconnects and high-frequency components such as antennas, RF/microwave components and biomedical devices. With HFSS, engineers can extract scattering matrix parameters (S,Y, Z parameters), visualize 3-D electromagnetic fields (near- and far-field) and generate ANSYS Full-Wave SPICE models that link to circuit simulations. Signal integrity engineers use HFSS within established EDA design flows to evaluate signal quality, including transmission path losses, reflection loss due to impedance mismatches, parasitic coupling and radiation.
Each HFSS solver is based on a powerful, automated solution process where you are only required to specify geometry, material properties and the desired output. From there HFSS will automatically generate an appropriate, efficient and accurate mesh for solving the problem using the selected solution technology. With HFSS the physics defines the mesh; the mesh does not define the physics.
HFSS 14.0 Major Enhancements
- Antenna array setup and analysis using domain decomposition
- IE regions on conducting surfaces and dielectric objects
- Transient simulation enhancements
Available renormalization and Y/Z parameters when passive ports are present
Usability improvements in Edit Sources
Available scaling and time delay settings for solved sources
- Huray surface roughness model
- DC continuity check
- Interpolating sweep with passivity check
- Physical optics (PO) solver in HFSS-IE
- 64bit UI
Known Issues
- The 3D modeler could exhibit sluggish behavior in a dual monitor configuration with certain graphics cards.
- Users should be aware that in Transient designs (not Transient Network) a wave port terminal inherits the active or passive status defined in the Propertywindow for the wave port. So, if you would like to assign a passive terminal make sure that both the wave port AND the terminal are passive.The wave port must be set by unchecking the Active checkbox in the Property window.
- Catia v5 models cannot be imported into HFSS 14.0.
