# Post-Processing Using Ansys HFSS — Lesson 4

Good results are a reward for your hard work. This lesson teaches how results and field plots can be viewed post-simulation in Ansys HFSS.

This lesson consists of one lecture and two workshops.

This lecture covers the theoretical aspects of various plots and field patterns. It tells how S parameters can be plotted and compared. It also shows how field quantities like electric field, magnetic field, surface currents, etc., can be overlaid on the design geometry for better interpretation.

### Workshop 4.1

This workshop covers the simulation aspects of the S parameter and fields of a coax tee. The outline for this workshop is as follows:
open AEDT >> open coax tee design >> simulate it >> plot S parameter for all three ports >> select design geometry >> plot electric field

### Workshop 4.2

This workshop covers the simulation aspects of the Smith chart and field plots for the patch antenna. The outline for this workshop is as follows:
open AEDT >> open previously simulated rect inset fed patch antenna design >> create S parameter Smith chart >> select geometry >> plot electric field
