Hi all,

i've to simulate a body rotating in a open field. My problem is that using dynamic mesh (wall set as rigid body motion) the elements degrade really fast becoming more and more larger.

I'm using fluent 13, unstructured grid (tri - 2D) with no boundary layer (prismatic layer) on walls.

I think there is something wrong in remeshing setting. Any advice?

Thank you

The size function of the remeshing and smoothing may be helpful.
AND I wonder whether your steady simulating results of stationary rigid body using the same unstructured grid are similar to those of the experiment or results using structured grids.
