Dynamic Mesh For a Poppet Valve
 

Hello,

I've correctly simulated steady state scenarios of a poppet valve but when I tried to create a dynamic mesh I found that this makes the problem much harder and it's hard to find any information on it. Tutorials only go so far in a few minute videos, does anyone have recommendations? All I want to do is stroke a poppet 4 mm in a 2D axisymmetric layout.
