I am facing problem running the simulation at first simulation was aborted due to large minimum increment for the model now too many attempts made for this increment.

Errors
Too many attempts made for this increment

Abaqus/Standard Analysis exited with an error - Please see the message file for possible error messages if the file exists.

Warnings
*friction,lagrange or *friction,rough may cause convergence difficulty when used in conjunction with the *surface behavior, augmented lagrange or penalty option. Use penalty friction instead.

For contact pair (assembly_slave-assembly_master), adjustment was specified but no node was adjusted more than adjustment distance = 2.22000e-16.

139 elements are distorted. Either the isoparametric angles are out of the suggested limits or the triangular or tetrahedral quality measure is bad. The elements have been identified in element set WarnElemDistorted.

The strain increment has exceeded fifty times the strain to cause first yield at 6 points

The strain increment has exceeded fifty times the strain to cause first yield at 14 points

The strain increment is so large that the program will not attempt the plasticity calculation at 5 points.

You have some significantly stretched elements in the contact area (in the undeformed model). This region has to be remeshed. Also make sure that your model is stable in all steps (no rigid body motions).
