On the File menu, click Open. Browse to the HFSS 8.5 projects’ directory, and open the *.pjt folder of a specific project. Select Ansoft Legacy EM Projects (*.cls) from the files of type pull-down list. Select the *.cls file in the project directory and click Open. The project appears in the HFSS v9.0 interface. NOTE: The HFSS v9.0 project is saved as a *.hfss file, and it is located in the user’s chosen project directory.

The selected solution data is placed in the ‘Imported Data’ window under ‘Current Imports’. Click ‘OK’ again to end the importation process. The user will be able to view or plot this imported data in the 2D Report editor.

Migration or re-classification of HFSS v8.5 projects to HFSS v9.0 is easily done using the Ansoft Legacy EM .cls file. When migrating a legacy HFSS project - a project created in Ansoft HFSS version 8.5 or earlier - virtually all of the project’s preprocessing data is migrated. Solution results are not migrated directly; however, HFSSv8.5 solution data will be available for plotting and tabular purposes. Optimetrics setup data are not migrated; however, the nominal model created for Optimetrics will be available in HFSSv9.
