Hi All,<\/p>\n

I am having a snap problem using Hex elements. I am facing some initial penetration, its solving almost 50% and then I am facing element formulation error, I found out that this is due to the initial penetration of the model, I tried using Augmented lagrange with Stiffness factor as 10, Still i am getting some penetration, its stopping, Same thing I tried with Normal Lagrange as well. the result is the same. The image shown at the bottom is of normal lagrange. Any idea how to solve this. I am getting convergence in tet mesh. I wanted to try with Hex elements to reduce computational time. Also to avoid the difference of Stress distribution in unaveraged and averaged. Can anyone help? <\/p>\n
