Regarding Indentation

I am carrying out indentation process.
But getting some problem. My indenter sphere center is at 2.1035 and radius is 1.965 units. From visualization, the indenter is already plunged into the workpiece in the beginning itself. However it should maintain some gap according to given command. I am attaching the program and screenshot for the first step. Kindly suggest.

ohh, I think it is mixed due to very less gap of the order of 0.5 A which is even quite smaller than bond length.
