Powerful Post-Processing Capabilities

HFSS provides powerful post-processing features to visualize, animate and report the results of your simulation.

  • S-parameters (single-ended, differential, de-embedded, renormalized)
  • Y and Z matrices
  • Port mode and impedance calculation by 2-D eigenmode solver fields
  • E and H fields, current densities, material losses, Q factors, radiation losses
  • Radiated-field calculations (directivity, gain, beam width, side-lobe levels, axial ratio, etc.)
  • SAR calculation

  • Plots
    • 2-D/3-D Cartesian/polar plots, Smith charts and Data tables
    • Overlay measurement data
    • Copy vector graphics to clipboard
    • Display trace characteristics, markers, delta markers and X markers
    • Copy and paste of plot definition or data from one report to another
    • Library of report templates: Create templates from reports and vice versa


  • Port surface characteristic impedance
  • Differential S-parameter, TDR display
  • 3-D static and animated field plots on any surface
    • Current, electric field, magnetic field
    • Radiation pattern, emissions test
    • Vector display, magnitude display
  • Ranged Functions: Extract calculations, such as maximum, minimum and average, from a plot or dataset
  • Multi-processing for mesh and post-processing operations
  • Adjoint derivatives direct calculation of the derivatives of S-parameter with respect to variations in geometry, materials and boundary conditions
