**v6.04.203** SSNV203 — Applying pressure to the lips of a crack with X- FEM
==========================================================================================

**Summary**

The purpose of this test is to validate the imposition of Neumann conditions (flow conditions) on the lips of a crack by the X- FEM [:ref:`bib1 <bib1>`] method on a 2D/3D academic case. In fact, we only consider the case of an interface, the case of a crack is considered in the ssnv185a and ssnv185c test cases.

This test involves a 2D then 3D structure including a flat interface. Pressure boundary conditions are applied to this interface.
