2. Modeling A#

This is” 3D “modeling, in thermal and mechanical terms.

2.1. Characteristics of the mesh#

The mesh contains all types of linear meshes that can support finite elements X- FEM in “3D” modeling. The cracks are arranged in such a way that all the X- FEM elements of the modeling are tested. The mesh, as well as the two cracks considered (a circular crack and an interface) are represented in the figure below.

The mesh also contains two orphan nodes, from which two POI1 meshes are constructed to assign two MECA_DIS_TR_N elements.
