Hi, I am a student and I try to learn Ansys Fluent. I have a project and want to see approximately how much pressure is it needed to swell. Which analysis type do i use? It is elastic, therefore i am confused.

Here is the link: https://www.youtube.com/watch?v=GgJt6vIbiso (If you do not wonder how it is made, you can watch the last minute.)

I doubt if this can be done using Fluent. The flow is not so interesting here. The shape (i.e. deformation) is not determined by flow but by the pressure. So you'd better focus on the mechanical part. Not sure what mechanical software can do this.

Not CFD software, as Gert-Jan says.
This would be a mechanical analysis with geometric non-linearities, and probably material non-linearities included. Most commercial FEA packages should be able to do this. ANSYS mechanical static-structural for one. Transient-Structural is not needed, as inertia is not a role here for the most part.
