Overview
During the 2001 Ansoft HFSS/Ensemble Users’ Workshop, Ansoft introduced the first
release of the Power Plug-Ins. The Power Plug-Ins were developed to improve the overall
simulation experience by providing new levels of customization and integration for users.
Building on the existing foundation, the Power Plug-Ins have been extended to include
Smart Simulation Wizards that target the stand-alone Ansoft HFSS and Ansoft HFSS with
Optimetrics simulation environments. In addition, the next generation of Power Plug-Ins
introduce Smart Simulation Wizards for managing information in a mixed simulation
environment that combines circuit and electromagnetics simulation engines.
The Smart Simulation Wizards simplify the simulation experience and enable even
novice/casual users to take advantage of the functionality and power of the Ansoft HFSS
Design Environment

Smart Simulation Wizards
Building on the Power Plug-Ins foundation, a new type of plug-in has been developed to
provide intelligent modes of operation. The Smart Simulation Wizards detect and
customize their appearance and functionality based on their operating environment.
The Smart Simulation Wizards support a stand-alone Ansoft HFSS and Ansoft HFSS with
Optimetrics environment. Custom operation modes ensure successful design by creating
design guides that harness the power of Ansoft HFSS.
Smart Wizards create useful design templates that are used to automatically extract
simulation information that can be used by the designer or passed to Ansoft Optimetrics
to produce design curves. These templates are intended to provide automated-assistants
for the setup of complex designs, simulations, optimizations, and co-simulations.
Each Smart Simulation Wizard provides the following functionality:
Automatic Solution Detection(Modal, Terminal, etc.)
Ansoft Optimetrics Awareness
Automatic Plot File Generation
Automatic Data Extraction(Min, Max, Average, etc)
Automatic Plot Preview(Stand-Alone mode Only)
