Hi all, I have been performing contact analysis in Abaqus; I have given frictional interactions between two surfaces(contact pairs) with default conditions. The analysis is getting aborted with errors like too many attempts made for this increment (but the last increment was close to 10e-15, step is up to 5U). Warnings are 2 unconnected regions in the model and negative eigenvalues. I have repeatedly remodeled to rectify the unconnected regions, but still, I see the same warning. I have attached the monitor tab; please look into it. 

Any answer is helpful.

Thanks in Advance.
