Contact and thermal expansion

I am having a big problem with contact, I realise that It has to be a parametric study as transiant is not supported. I have a stack of cylinders (like a stack of coins) the upper most boundary and the lower most are fixed or set to symmetric boundary. The temperature of the cylinders is the varying parameters, there is a coulomb contact friction between the cylinders of 0.8. Every time the model fails to converge from the augmented Lagrangian solver. All the advice in the documentation has been followed the cylinders are meshed appropriately for their master and slave configuration. I have even tried the tip in the documentation of letting them over lap and have the contact algorithm force them apart. In the documentation they have no physics based drivers for contact it is all prescribed displacements.
Any advice on how to proceed would be greatly appreciated. I have been stuck for quite some time. and am a little bit concerned that this can be done in abaqus in a few minutes.
