Ansys Electronics Suite: which solver fits your job?

Ansys Electronics Suite is for analysing the electromagnetic and thermal behaviour of electronic designs, not for drawing schematics alone. In Ansys Electronics Desktop, the practical choice starts with the quantity you need: antenna response, conductor parasitics, magnetic force, board-level power integrity, or heat removal. The applications share an engineering environment, but each solver answers a different physical question.

Ansys HFSS for RF and antenna analysis

With an antenna, microwave filter or RF connector, define the 3D geometry, materials, ports and operating frequencies. HFSS calculates electromagnetic fields and produces results such as S-parameters and radiation patterns. It is suited to wave behaviour and coupling at radio and microwave frequencies.

Ansys Q3D for parasitic extraction

Q3D Extractor addresses the unwanted resistance, inductance and capacitance of interconnects: for example, a package lead, busbar or connector. It extracts RLGC parameters and circuit models that can be used to evaluate losses and coupling. This is a quasi-static extraction task rather than a replacement for a full-wave antenna simulation.

Ansys Maxwell for electric machines

Maxwell handles low-frequency electromagnetic behaviour in motors, transformers, coils and actuators. An engineer can define winding excitations and magnetic materials, then investigate flux, force, torque and losses. Choose this path when magnetic-device performance is the design question, rather than PCB signal integrity.

Ansys Icepak for electronics cooling

Icepak tackles temperature and airflow in electronics. A board or enclosure model combines component heat loads with the cooling arrangement to estimate temperature distribution and airflow. Thermal results are a different output from HFSS field plots; any electrothermal exchange needs an appropriate coupled analysis setup.

Ansys SIwave for PCB signal and power integrity

For a populated PCB or package, SIwave evaluates current return paths, power delivery and signal-integrity effects across the layout. The outputs can help locate voltage-drop or coupling problems before a board revision. It complements conductor-level Q3D extraction and 3D HFSS analysis rather than replacing either.

Ansys Electronics Suite applications by engineering task

• EMC verification: simulated interference or field levels inform a design, but do not replace the required physical compliance tests.
• Thermal verification: Icepak temperature predictions depend on realistic power dissipation and cooling boundaries, not just the geometry.

Ansys Electronics Suite 2024 R2: choosing a release

In 2024 R2, Ansys introduced the commercial Phi+ mesher in HFSS 3D Layout and documented faster, more robust meshing for rigid-flex designs. Those improvements may matter when a layout is large or difficult to mesh; they are not a reason to change a validated motor or transformer workflow automatically.

Ansys Electronics Suite Windows 10 and Windows 11

These are release-specific supported Windows families, not a claim that Windows Home or every individual hardware configuration is supported. Ansys specifies Professional, Enterprise or Education editions for the applicable desktop releases.
