However, HFSS v9.0 will be able to import various types of file formats such as:
w w w w
*.szg files (HFSS v8.5 native file which contains all information about S-Z-Ygamma-Zo solution data) which is located in the project’s directory, or *.flp files (Serenade/Ansoft Designer), or *.sNp, *.yNp,*.zNp, *.tou files (Touchstone), or *.tab file (tabular file that can be exported from v8.5 Post Process > Matrix Data module).

After importation data can be plotted using the Results Post-processor
Importing data from HFSS v8.5
w w w
Right-click on Analysis in Project tree, select ‘Import Data’ or ‘Import Table’ From the Imported Data window, select either Import Solution to Load File Browse to the specific format file After the ‘Load File’ step, select the type of ‘Available Solutions’ desired (e.g. adaptive1,…, sweep1), and click ‘OK’. 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.

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.

Legacy Project Migration
Legacy Project Migration

w w
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.

Impedance Lines and Terminal lines are migrated.
– Impedance lines will be ignored for Driven Terminal solutions, terminal lines will be ignored for Driven Modal solution.

Projects that contain terminal lines are migrated to Driven Terminal solution projects Current meshes are not migrated, only initial mesh is. Impedance-only and emissionsonly solutions are not migrated. Saving dominant-only or higherorder-only mode S-matrix entries are not migrated For frequency sweeps, the Number of Steps value is migrated to the corresponding Step Size value The total number of requested adaptive passes in the legacy project is migrated as the Maximum Number of Passes
Most Boundaries are migrated

Boundaries assigned to named interface selections or rectangle selections are not migrated.
