Vast Mesh Motion

Shuto

Hi all,

I am using Fluent to move a 4m car over 100m in a straight line through an unstructured dynamic mesh. I am trying to maintain cell refinement close to the body, within about 10m, but Fluent keeps introducing huge cells.

I have varied every possible parameter and been through all the tutorials and still can't resolve this. Can anyone offer some practical advice?

Thanks, Shuto.
