Hello all,  
after several tests, I have noticed that if the mesh (on which contact surfaces (master and slave) are built) is not coicident nodally , the output in terms of stress are different than Abaqus.  
Did you notice this problem?

How big is the difference ? Are the contact settings the same ? Abaqus may use different defaults.
