Good day guys.

I have a doubt about the option "all with self" in the contact domain in general contact. I have read the abaqus information but is not enough clear for me. Is necessary to specify the contact domain selecting surface pairs knowing that in the attribute assignments the surface pairs have to be specified again? Or if I put in the contact domain "al with self" and in the attribute assignments put the surface pairs is the same?

Thanks for your orientation.
