Divergence in Transient solver

I've been trying to model a 2D vertical axis wind turbine using a transient solver. I had a tutorial which helped me a lot set up my problem and my code which defined the motion of the blade.
The blade motion is defined by the equation of motion of of a four bar linkage.
I can preview the mesh motion, which is what i need. The problem is that the solution diverges after only 10 iterations !
Do you reckon it's a problem from my code? (but the mesh motion is correct), or the mesh itself(which i highly suspect) or maybe the setup! (what is usually a key factor contributing to divergence in transient solvers)

could be anything actually.
How do you know the mesh motion is correct? Remeshing? Morphing?
P.S.: try to solve ONLY for the mesh motion without any u,v,w,p,eps,...
