3. Model A#
3.1. Characteristics of the model#
In this model, the crack is meshed (FEM case). The underlying modelisation is 3D.
We use the SYME=YES keyword for the crack.
The result rmed has been generated beforehand.

3.2. Characteristics of the mesh#
Number of nodes: 317
Number of cells and type: 562 POI1, 24 SEG2, 9 TRIA3, 239 QUAD4, 12 PENTA6, et 180 HEXA8.
3.3. Performed calculations#
The POST_J operator is tested against POST_K1 and CALC_G option G.
3.4. Tested values#
