Key Use Cases
What is ANSYS HFSS
The global standard for high-frequency EM simulation
ANSYS HFSS (High Frequency Structure Simulator) solves Maxwell's equations in full 3D using the Finite Element Method with automatic adaptive mesh refinement. Since 1990, HFSS has been the mandatory tool for RF and microwave engineers designing antennas, filters, waveguides, and complete RF front-end systems.
Unlike simplified circuit simulators, HFSS captures all electromagnetic phenomena — radiation, coupling, resonance, surface currents — with full vector accuracy. Results correlate with physical measurements even for densely integrated, multi-layer structures. CADFEM Ukraine is the sole authorized ANSYS Channel Partner in Ukraine providing official HFSS licenses, English-language training, and EM consulting.
Full-wave 3D EM accuracy
HFSS solves Maxwell's equations in full 3D with automatic adaptive meshing (AFE) — no manual mesh tuning. Results match lab measurements even for complex curved geometries and tight coupling structures.
Multiple solvers in one package
Driven Modal, Driven Terminal, Eigenmode, SBR+ (ray tracing for electrically large objects), IE (Method of Moments), FDTD — all accessible from one Workbench interface without additional licenses.
True multiphysics integration
Coupled EM-thermal-structural workflow: HFSS computes Joule heating → Icepak or Fluent for cooling → Mechanical for thermal deformation → HFSS for deformed antenna performance. All within ANSYS Workbench.
Parametric optimization for RF design
HFSS Optimetrics automates parametric sweeps, impedance matching, pattern optimization. Integration with ANSYS optiSLang enables full DOE and robust design workflows for antenna and filter development.

+38 (050) 454-37-54What is ANSYS HFSS and what problems does it solve?
+
ANSYS HFSS (High Frequency Structure Simulator) is a 3D full-wave electromagnetic field solver based on the Finite Element Method (FEM). It solves Maxwell's equations in full 3D with automatic mesh adaptation, providing results that accurately match physical measurements. HFSS is used to design antennas, microwave filters, waveguide components, 5G mmWave arrays, radar systems, and to analyze EMC/EMI of electronic assemblies. It is the global industry standard for RF and microwave engineering.
What is the difference between HFSS and ANSYS Maxwell?
+
ANSYS HFSS targets high-frequency problems (MHz to THz range): antennas, filters, waveguides, 5G, radar — where the device dimensions are comparable to or larger than the wavelength. ANSYS Maxwell targets low-frequency problems (DC to ~100 MHz): electric motors, generators, transformers, inductors — where quasi-static approximations apply. If your frequency is above ~100 MHz and you care about radiation, wave propagation, or distributed effects — use HFSS.
When should I use HFSS SBR+ instead of standard HFSS FEM?
+
Use HFSS FEM for structures that are on the order of a few wavelengths in size — antennas, filters, connectors, PCB transitions. FEM solve time grows with electrical size. Use HFSS SBR+ (Shooting and Bouncing Rays) when the platform is electrically very large — an aircraft, ship, or ground vehicle. SBR+ is based on ray tracing and scales independently of platform size, making it orders of magnitude faster for RCS computation and antenna-on-platform pattern analysis.
Can HFSS model 5G massive MIMO antenna arrays?
+
Yes. HFSS has specialized large-array capabilities: HFSS Array — unit cell approach for infinite regular arrays with Floquet ports; Domain Decomposition Method (DDM) — parallel decomposition of large finite arrays across multiple cores; Finite Array DDM — accurate finite-array analysis combining unit cell and edge effects. All major 5G element types are supported: patch, slot, dipole, end-fire, Yagi.
How does HFSS integrate with thermal analysis for antenna derating?
+
In ANSYS Workbench: HFSS computes EM fields and Joule heating losses in conductors and dielectrics → Icepak or Fluent performs conjugate heat transfer to determine component temperatures → ANSYS Mechanical computes thermal deformations of the structure → deformed geometry is fed back into HFSS to assess performance degradation. This coupled EM-thermal-structural workflow is the standard approach for high-power antenna and amplifier design.
Does CADFEM Ukraine provide HFSS support and training in English?
+
Yes. CADFEM Ukraine has a dedicated English-speaking engineering team. We provide: technical support for HFSS installation and usage, English-language HFSS training courses (classroom and online), EM simulation consulting with English-language deliverables, and assistance with ANSYS license procurement. This makes us the preferred HFSS partner for international defense contractors, telecom companies, and engineering teams in Ukraine.
