Re: [deal.II] question on contact algorithm for step-41

Hoang, I have some doubts over the contact algorithm used in step-41. Maybe someone can help me to clarify: + In step-41, instead of solving for delta_U and delta_Lambda, we solve for U_k+1 by using a finite difference equation. Is it some form of explicit contact algorithm? I'm not familiar
