v6.04.198 SSNV198 — Dirichlet conditions with X- FEM in 3D

Summary

The purpose of this test is to validate the imposition of Dirichlet conditions (imposed movements) on nodes enriched by the X- FEM [bib1] method on a 3D academic case.

This test involves a 3D structure including a flat breakthrough crack with a straight bottom. Boundary conditions are applied to one face of the structure, containing enriched nodes.

Several mesh configurations are tested and compared with the analytical solution.
