How to optimize E_N Penetration contact coefficient in Code Aster?

In the previous nonlinear leaf spring tutorial (part 2), I have mentioned that there are ways to optimize the E_N penetration contact coefficient.

This is a procedure which is usually done recursively by choosing a coefficient, checking the penetration and then increasing the value until a good solution is obtained.

In Code_Aster, there is a command that will automatically check the penetration and increase this E_N coefficient. Isn’t that nice?

This short video will teach you how:
