Conclusions =========== This document brings together the information elements available on the X- FEM method in*Code_Aster*. The limits and possibilities of X- FEM are recalled, and examples of implementation in a case without and then with contact are presented. In the future, this document will be supplemented by: * the use of error indicators for X- FEM, * post-processing of contact terms on the visualization model. .. _Ref375039773: .. _Ref374957480:
