As noted earlier, Ansys Polyman creates a .prj file for each new project. To reopen an existing project, you will select the corresponding .prj file.

You can open an existing project from the menu bar:

File → Open...

or by typing Ctrl-O

or by clicking the corresponding icon in the toolbar.

In the Choose a file panel, select the .prj file for the desired project, and click OK.

The four projects that you accessed most recently will appear at the bottom of the File menu. You can select one of these as a shortcut. Also, on a Windows system, you can double-click a .prj file to start Ansys Polyman and open the selected project.
