There is some useful information to be gleaned from the f06 output... it is showing that the solution is progressing pretty well, in the sense that it took 5 iterations for it to converge at 50% of the total load, then it took 3 iterations at 60% and 70%... the fact that the load convergence criteria is already 'converged' at the first iteration (unless the default of 10% has been changed, but even so, it is less than 1%) implies the iterations are most likely from contact separations.
There should be another output file that has a .sts suffix... it is a more concise summary and can help you see what is going on... here is a sample:
You can see where there are a lot of iteration (cycles) and separations, as well as any load cut backs.
