problem with contact pairs in abaqus

[jj89]

Hi all,

I have a semicone with two different friction coeficient (Coulomb law) the first half part of the semicone is frictionless and the second is 0.2,
A material is formed going through the semicone and I am not sure how I should define the contact because apear appears a warning:

*******************
THE SLAVE SURFACES ASSEMBLY_SUP_ALU AND ASSEMBLY_SUP_ALU_2 INTERSECT EACH OTHER. THEY ARE PAIRED WITH MASTER SURFACES ASSEMBLY_CUERPO AND ASSEMBLY_ROCE THAT ALSO INTERSECT EACH OTHER. IF BOTH PAIRS ARE *CONTACT PAIRs, THESE TWO PAIRS SHOULD NOT BE SIMULTANEOUSLY PRESENT IN A STEP BECAUSE OF POSSIBLE CONVERGENCE PROBLEMS; USE *MODEL CHANGE,TYPE=CONTACT PAIR TO REMOVE ONE OF THEM. IF BOTH ARE *TIE PAIRS, THE REDUNDANT TIES WILL BE REMOVED AUTOMATICALLY. IF ONE PAIR IS *TIE AND ANOTHER IS *CONTACT PAIR, REMOVE ONE OF THEM.
*******************

How I did:

I created two contactes "surface to surface contact(standard)" in every one i define whole piece with every semisurface of the semicone.

If you need any clarification just ask!! Thanks a lot!!!

At least the master regions shouldn't intersect each other.
