**v6.04.186** SSNV186 — LBB condition and rubbing contact with X- FEM
====================================================================

**Summary**

The purpose of this test is to validate the consideration of contact (by the continuous method [:ref:`bib1 <bib1>`]) on the lips of the crack as part of the X- FEM [:ref:`bib2 <bib2>`] method, when the LBB condition [:ref:`bib3 <bib3>`] [:ref:`bib4 <bib4>`] is not respected.

Contact/friction is treated by an augmented Lagrangian algorithm for A to H models and by a penalized algorithm for I to K models.

This test involves a parallelepipedic block in compression. The interface crossing it is represented by a level set. The interface is straight, non—leaning, and goes all the way through the elements.
