Dynamic Meshing 2D whole domain translation
1 Attachment(s)

I am trying to mesh a solid falling through a fluid. This will be solved via fluent (6DOF problem). My problem is that the entire domain translates instead of just the solid that should be falling through the fluid medium (but at least the velocity values seem to be correct). I have stripped this down to as simple a problem that I could.
It's a 2D geometry, with constant temperature. For this initial case all I want to be able to see is how the solid will move through out the liquid if small perturbations attack it from various angles.
I feel that this is a meshing problem, as I have been able to run through several different tutorials with no problems. I have the fluid set up as triangulation and then a group of quads around the solid.
the mesh I attached is obviously wrong, but it shows the three distinct zones.
Let me know if you can help.
