Relaxation problem during each indentation step

Hi,

I was trying to indent the bulk Al2O3 with a spherical indenter. I have done the indentation in several steps using nested loop algorithm in LAMMPS. In that case I want to do relaxation after each indentation step while considering the indenter to be in place. And the problem with relaxation was when I did the relaxation, the simulation results looked like that there is no indenter present. So how I can implement the relaxation after each indentation while considering the presence of indenter into account. I have attached my LAMMPS inputs to this email.
