• The Families Tab
• • • •
When solutions exist for multiple variations of the design the Families tab allows users to choose which variation’s data is used If multiple variations are selected each one shows up as an additional curve The button in the Edit column allows finer control over which variations are included Variables can be set to their nominal values to simplify the list – Nominal values are the current values these variables are set in the design.

Field Overlays
• Field Overlays
• Field Overlays create contour plots that are applied to geometric surfaces or volumes • The quantities plotted are directly derived from the volumetric E-Field solution HFSS solves with in the solution domain.
