Dynamic Mesh Motion
 
I am an OpenFOAM beginner, so I apologize in advance for any ineptitude.

I am attempting to mesh an object which, upon being pushed by the fluid, moves. It is VERY much like the wingMotion tutorial. However, after a bit of time running, it crashes - the mesh, at this point, has stretched greatly. Is there any way I can prevent the mesh stretching? I know the mesh can move with the object (movingCone) but what if the motion isn't prescribed?

I believe the mesh stretching is the issue since if I modify the wingMotion tutorial to move a lot more (thus stretching a lot more) I get an identical crash.

Any ideas? Thank you for your time.
