**d4.10.02** Data Structures linked to X- FEM
================================================

**Summary**

This document describes the data structures (SD) related to the X- FEM method. These objects are in several SDs:


1. sd_fiss_xfem, produced by the operator DEFI_FISS_XFEM [:external:ref:`U4.82.08 <U4.82.08>`] and used for a fracture mechanics calculation as part of the X- FEM [:external:ref:`R7.02.12 <R7.02.12>`] method. This data structure is also used and produced by the operator PROPA_FISS [:external:ref:`U4.82.11 <U4.82.11>`],


2. sd_modele_xfem, produced by operator MODI_MODELE_XFEM [:external:ref:`U4.41.11 <U4.41.11>`],


3. SDs created for contact resolution..
