convergence issues in structrual mechanics problems : inverted mesh elements...

I am using the latest version of COMSOL 4.3 and working with the new implmented creep features with user defined creep equations.
I have problems with convergence due to think layer geometry and i tried all what i can with meshes (as fine as possible with free triangular elements), time steps, solver settings to get my model working. the issue seems related to large deformations and also tried to include geometric non-linearities but i dont see any difference.
would you check out my model (attached) and give me your recomendations please? i appreciate your concerns
Thanking you a lot
