Is the Additive suite available in the student version? The "AM Process" button is available but when clicked is giving this error:
What's included in Student is listed here, https://www.ansys.com/academic/free-student-products but doesn't look to have the AM suite. It may be available via the Research licence (your University may have those available) or could require a commercial licence. Check with your supervisor/department Ansys contact and if necessary use the Contact Us route to get to the Sales team.
