Hi,

I'm modeling a simple oscillation and I use structured grid and Dynamic mesh,
I've attached a schematic of the model,
I'm applying a simple oscillation motion to the moving boundary and I want the whole domain moves compress and expand,
but for my domain the cells near to the moving boundary compress more than each other, so after a while they turn to negative volume cells,
What do you recommend me for solving the issue?
