Hello,
i am writing this post because i can not find the solution to my problem. I hope any of you guys know the answer.

I am trying to analyse the heat conditions in compressible fluid (helium) and how the heat is transferred to the surrounding wall.

I am having a trouble regarding dynamic mesh simulation. The problem arises when i try to preview a mesh motion under Dynamic mesh panel. I want to use Layering method with block structured mesh created in ICEM. When i run mesh preview some vertices stay connected with the vertices on the wall. Regardless what settings i use i can not disconnect vertices on the wall and piston.

This is just a simple 2D example that i wish to solve before moving to original 3D problem. I hope you know what i am doing wrong.
