dynamic mesh not deforming in fluent
 

Hi Guys,

I am doing FSI with strong coupling for a flexibale valve. I defined dynamic mesh, system coupling for the fluid-solid interface in the fluent but the mesh in fluent is not deforming while the valve deformed in transient structure solution. the mesh type is all tetrahedrone for the fluent. please see attached file to have a better understanding of the problem.
Thank you in advanced guys to helm me out.

I am also doing a fluid structure interaction problem. Let me know if you find anything.....I am simulating a piston moving up and down.

Dynamic mesh for piston moving up and down
 

Hi Everyone,

I am simulating a dynamic mesh simulation. The issue is with the in-cylinder settings. Does anyone have experience with the setup of these simulations to help out?
