The Ansys HFSS simulation suite consists of a comprehensive set of solvers to address diverse electromagnetic problems ranging in detail and scale from passive IC components to extremely large-scale EM analyses such as automotive radar scenes for ADAS systems. Its reliable automatic adaptive mesh refinement lets you focus on the design instead of spending time determining and creating the best mesh.This automation and guaranteed accuracy differentiates HFSS from all other EM simulators, which require manual user control and multiple solutions to ensure that the generated mesh is suitable and accurate.

Users can take advantage of the seamless workflow in Electronics Desktop, which includes advanced electromagnetic field solvers, and dynamically link them to power circuit simulators to predict EMI/EMC performance of electrical devices. These integrated workflows avoid repetitive design iterations and costly recurrent EMC certification tests. Multiple EM solvers intended to address diverse electromagnetic problems, as well as the circuit simulators in Electronics Desktop, help engineers assess the overall performance of their electrical devices and create interference-free designs.

EMIT’s powerful analysis engine computes all important RF interactions including non-linear system component effects. Diagnosing RFI in complex environments is notoriously difficult and expensive to perform in a testing environment, but with EMIT’s dynamic linked results views, the identification of the root-cause of any interference is rapidly accomplished via graphical signal trace-back and diagnostic summaries that show the exact origin and path that interfering signals take to each receiver.

A candidate array design can examine input impedances of all elements under any beam scan condition. Phased array antennas can be optimized for performance at the element, subarray or complete array level based on element match (passive or driven) far-field and near-field pattern behavior over any scan condition of interest. Infinite array modeling involves one or more antenna elements placed within a unit cell.

It includes EMIT, a unique multi-fidelity approach for predicting RF system performance in complex RF environments with multiple sources of interference. EMIT also provides the diagnostic tools needed to quickly identify root-cause RFI issues and mitigate problems early in the design cycle.

HFSS with SI Circuits can handle the complexity of modern interconnect design from die-to-die across ICs, packages, connectors and PCBs. By leveraging the HFSS advanced electromagnetic field simulation capability dynamically linked to powerful circuit and system simulation, engineers can understand the performance of high-speed electronic products long before building a prototype in hardware.

The ability to simulate encrypted HFSS 3D components means that you no longer need to compromise on accuracy. Designers are no longer forced to use circuit-level components (e.g., S-parameter models) vs. true 3D models into their design, impacting the overall simulation accuracy. It enables prospective customers of vendors to use encrypted 3D Components in a full system design.

HFSS multipaction solver is based on a finite-element particle-in-cell (PIC) method. HFSS provides the multipaction analysis as a postprocessing of the frequency-domain field solutions. With few steps to set up the excitations and boundary conditions for charged particle simulation, you can check whether your design meets the standard for multipaction breakdown prevention.
