Dynamic mesh settings?
 
I'm trying to model a cylinder within fluent, but I'm encountering errors with the dynamic mesh. After some time as the piston wall moves across and the cylinder walls deform the mesh becomes bunched up and then fails with a negative volume error.

Any ideas? It's been driving me crazy for a week.
