### Contact of a rigid indenter on a block

Hi All,

I have been trying to model contact of a rigid indenter in contact with a block using large deformations (hyperelastic material).The source i have come across to model contact is using the constraint optimization solver snes or Tao. However, I couldn't figure out how i would be able solve this problem using these solvers. Can a lagrange multiplier based penalty method be implemented for multi-body contact? Or is there a procedure of using the constrained optimzation solver to solver the problem? Any ideas or help is really aprreciated.

Thanks in advance.
