Problem importing geometry in Ansys Mechanical

    • Luca Rutigliano

      When I first import the STEP/IGES or whatever file into ANSYS and execute the simulation saving then the project I have no problem. However, when I try to reopen the project, I don't know why this error message appears. It is happening with all my ansys projects in which I', ve imported the hìgeometry from a CAD, and it's only started recently, never had problems before these last 2 days. Any idea? All the files are saved in the same directory as always

      Have you checked the file path listed in the error to confirm if the file actually exists there? I don’t use Dropbox. A quick online search shows it is a cloud based storage and backup service. Is this path to the file possibly a symbolic link to the online location, and not actually the file on your local disk? If so, then it would no longer work if your internet connection was disrupted.

      Note that after you have transferred your geometry to Mechanical, it doesn’t matter anymore if the project can find the geometry, unless you want to make changes to the geometry in SpaceClaim or DesignModeler and refresh the geometry in Mechanical.

      Does it recognize the geometry file when you make a new analysis system, specify the step file on the Geometry cell and “Edit” the Model cell?

      It’s possible there is a character in the path it doesn’t like. Is that a vertical bar after the “I” or a capital I?:

      C:\Users\Utente\Dropbox\I| mio PC (DESKTOP-HP545G0)\Desktop\mode_superposition\beam.STEP

      Have you tried “View > Files” then right click on the red row to “Repair” and browse to the file?
