6) Incorrect Usage or Settings
Ansys is complex. Even if the software is installed and operating properly, incorrect project settings or workflow can cause errors. Maybe you're trying to do something one way, but Ansys needs it done in another, or doesn't support it all together. Maybe your model design or settings are not correct.
