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 [U4.82.08] and used for a fracture mechanics calculation as part of the X- FEM [R7.02.12] method. This data structure is also used and produced by the operator PROPA_FISS [U4.82.11],

2. sd_modele_xfem, produced by operator MODI_MODELE_XFEM [U4.41.11],

3. SDs created for contact resolution..
