Create a new model by introducing specific finite elements that can be crossed by an X-FEM crack from an existing model.

This operator makes it possible to modify certain classical finite elements into enriched finite elements; the elements to be modified have been determined beforehand by the operator DEFI_FISS_XFEM [:ref:`U4.82.08 <U4.82.08>`].

The new model thus defined can be used as input data in the rest of the calculations:


* to operators MECA_STATIQUE [:ref:`U4.51.01 <U4.51.01>`] or STAT_NON_LINE [:ref:`U4.51.03 <U4.51.03>`] if the initial model is a mechanical model;


* to operator THER_LINEAIRE [:ref:`U4.54.01 <U4.54.01>`] if the initial model is a thermal model.

The operator produces a model type concept.
