Blood flow in an aneurysm, in virtual reality

Simulating blood flow in an aneurysm before and after a stent is placed, then turning the results into a VR scene that clinicians and patients can both understand.

Meta QuestVR presentation

The question

How does placing a stent change blood flow inside an aneurysm, and how can that be shown clearly to people who are not engineers?

What I did

Prepared the vessel geometry and set up the flow cases in ANSYS.
Ran the model before and after placing a stent in the parent vessel, and compared flow inside the aneurysm sac.
Wrote MATLAB code to convert the ANSYS results into a 3D model (.obj).
Built the scene in Blender and presented it on a Meta Quest headset and in PowerPoint.
Designed the presentation for two audiences, clinicians and patients.

What I found

Turned complex flow data into a clear picture of the treatment outcome that specialists and non-specialists could both follow.
