Dynamic Mesh Problems

I have some problems in simulating a 3d store seperation with Fluent 13.0.
I am not sure if it is nessesary to use a cg-motion_udf in combination with 6dof_prop_udf for this movement. Is a 6dof_prop function sufficient?
The more important problem is the remeshing option. Everytime I get negative elements. I tried nearly everything I found about this problem. (reducing timesteps...). Finally it seems like this option doesn´t work with pyramide cells.
But my geometry is very complex and the boundary conditions are very important. Because of this I need a structured inflation. How can I manage this?
Is somebody able to help me? Thanks for your help.
