 One or more contact pairs are detected with a friction value greater than 0.2. If convergence problems arise, switching to an unsymmetric Newton Raphson option may aid in convergence.

what i do?

Do nothing if your model converges.  If it doesn't converge, it may be for reasons that have nothing to do with the symmetric solver, and switching to unsymmetric will not help, you have to fix the real cause of the failure to converge.
