Enhanced Solvers for ANSYS HFSS

For integrating systems such as satellites, aircraft, automobiles, and communications infrastructure combined with multiple antennas and communication systems onto a single platform, ANSYS HFSS is capable of handling the complexity and large problem size. Advanced methods in HFSS include improved matrix solvers, better scalability for HPC computing, improved mixed-order solutions and a distributed direct matrix solver. These enhancements allow HFSS to remain the gold standard with regard to accuracy and solving the largest and most challenging electromagnetics problems in the shortest amount of time.


Electromagnetics solutions must provide precise results within customer’s design flow. To streamline the customer’s experience, the HFSS for ECAD approach allows engineers to run complex 3-D HFSS simulations from a layout-based, ECAD environment. HFSS incorporates a faster mesher in the setup and an improved layer stackup dialog. The technology allows users to embed circuit elements directly from layout in an HFSS for ECAD simulation.

ANSYS HFSS 3-D full-wave electromagnetic field simulation can be integrated directly within a layout environment.

Wireless and Antenna Solution

HFSS has an improved current array simulation capability with the addition of an arbitrary array mask, allowing composite excitations, phase center calculations and arbitrary slant polarization far-field plotting. The technology also enables you to perform full-array visualizations. For the handheld smartphone segment, additional capabilities ensure hearing-aid compatibility and multi-in, multi-out (MIMO) calculations.

HF Electromagnetics to Structural Coupling

Fully coupled electrothermal-stress simulation is easier since you can link ANSYS HFSS to ANSYS Mechanical within ANSYS Workbench. Electrical loads computed by HFSS are passed to ANSYS Mechanical, which then can be used to simulate temperature increases and  associated deformation of the geometry. Those deformations can then be passed back to HFSS to allow further electromagnetic simulations and to evaluate the effect of the deformations.
