Berkovich indentation simulation problem

Dear all,

I am trying to simulated Berkovich indentation using abaqus recently. I am pretty new to FEM so currently having a lot of problems. I just build a 3D explicit model and it was able to give some results. But, the element penetration was serious. So I am posting this for help. Any kind of advice is appreciated.

For the model I built, I just use general contact for the interaction, even though I also tried surface-to-surface contact by defining the three inclined indenter surfaces the master and the sample surface the slave, respectively. I also checked the element deletion, and status variable. However, the status is not able to show in the field output dialog window.

Thanks for your time!
