sol106- contact algorithm

I have one question regarding the algorithm used in the contact analysis in sol106/101 with contact surface to surface

There are usually three algorithms (in the literature and implemented in other solvers):

- penalty

- aumented lagrange

- lagrange multiplier

 

Which is implemented? I can not see any option to change the algoritm? Maybe it is not possible?

Ok. Thanks Blas.

 

I was looking for the information in the handbook for nonlienar analysis
