I got a problem with a transient Simulation. It seems like a simple dynamic mesh problem, but whatever I try it won't work.
The geometry is a cylinder with one In- and four Outlets. The basic idea is that the fluid that is inside the cylinder will be pushed out and the geometry will be shrinking. I chose the Layering dynamic mesh method. I watched a lot of tutorials on youtube and they didn't help me with this problem. Am I missing something easy or is this actually a more complex simulation?
Thanks for your help,

Are you running 3D or 2D?

It is a 3d simulation

Ok. It should be very straightforward. Let me find out the getting started tutorial for you. Hold on!

Can you provide bit more detail about your model? how are you defining shrinking geometry? will there be a fluid flow from inlet to outlet?

Excuse me for answering so late, was a busy weekend. My idea was that a pressure inlet would push the fluid out of the zone, thanks to the dynamic mesh. There shouldn't be a fluid, just the pressure on the surface.

Hi Michael I have a 2D tutorial similar to your case which can be applied on 3D case

Thank you for the help. I found the mistakes in my setup.
