B modeling
==============


Characteristics of modeling
-----------------------------------

The modeling used is a C_ PLAN modeling.


Characteristics of the mesh
----------------------------

The mesh is the same as for modeling A.


Tested sizes and results
------------------------------

We test the values of the stress intensity factors given by the command POST_K1_K2_K3 (analytical comparison and non-regression) and the value of the error estimators for the 3 methods implemented in *Code_Aster* (parameters ERREUR_ERRE, ERREUR_ERZ1, ERREUR_ERZ2, ERREUR_QIRE,,,,,,, ERREUR_QIZ1, ERREUR_QIZ2) for the primal problem and the dual problem (non- comparison regression).
