1. But

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 [U4.82.08].

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

• to operators MECA_STATIQUE [U4.51.01] or STAT_NON_LINE [U4.51.03] if the initial model is a mechanical model;

• to operator THER_LINEAIRE [U4.54.01] if the initial model is a thermal model.

The operator produces a model type concept.
