ANSYS Savant - Technical Features

Installed Antenna Performance for Electrically Large Structures 

ANSYS Savant is the industry leading tool for simulating installed antenna performance on electrically large platforms, including the applications of predicting installed radiation patterns, field distributions, and antenna-to- antenna coupling. Savant simulations are configured through an intuitive and powerful graphical user interface (GUI) capable of importing and simulating complex vehicle and platform geometries that may be hundreds to thousands of wavelengths in size. A key element in Savant’s industry-leading status is its unique extensions to the shooting and bouncing rays (SBR) methodology, known as SBR+. Savant is the only commercial electromagnetic software to extend SBR with simultaneously consistent implementations of Physical Theory of Diffraction (PTD), Uniform Theory of Diffraction (UTD), and Creeping Wave to deliver maximum accuracy within a high-performance ray-tracing framework for large-scale problems.

In addition, Savant leverages GPU hardware for acceleration, utilizing both scientific computing and consumer-grade NVIDIA graphics adapters. For maximum throughput, Savant simulations can be massively accelerated through an MPI implementation that exploits the full potential of multi-core and GPU-accelerated HPC clusters. The new HFSS/Savant Datalink available in the ANSYS Electronics Desktop provides an easy yet powerful workflow where standalone antennas are simulated in HFSS and then directly imported into Savant for immediate placement and simulation on the platform using an accurate (near-field) representation of the antenna.

Specific enhancements in the ANSYS Savant release include:

  • Direct integration with ANSYS HFSS via the new HFSS/Savant Datalink
  • 3-D visualization of surface currents
  • Parametric simulations and Python scripting
  • Retain previous results within same project
  • Non-meter working units (cm, mm, inches, etc.)
  • Conformal arrays
  • Two new built-in antennas: horizontal dipole and circularly polarized cross-dipole
  • Modernized window management: dockable windows and dual monitor support
  • Performance improvements for dynamic zoning acceleration, UTD edge rays, and creeping wave

The new ANSYS HFSS-Savant Datalink provides a simple workflow for simulating freestanding antennas in  HFSS and then analyzing their installed performance on large-scale platforms in Savant
