7. Modeling E

7.1. Characteristics of modeling

Method GEOMETRIQUE is used by PROPA_FISS.

7.2. Characteristics of the mesh

The same mesh as that of modeling A. is used.

7.3. Tested sizes and results

We extract the normal (\(\mathit{LSN}\)) and tangent (\(\mathit{LST}\)) level set using the POST_RELEVE_T operator using the operator and we check that the maximum and minimum values remain included in the capture circle of the nodes tested around the crack front, i.e. \(2/3\):

\(\mathit{Propag.}i\)	\(\mathit{Max}{\mathit{LSN}}_{i}\)	\(\mathit{Min}{\mathit{LSN}}_{i}\)		\(\mathit{Max}{\mathit{LST}}_{i}\)	\(\mathit{Min}{\mathit{LST}}_{i}\)
3	0.235	0.397	0.397	0.333	0.272

The results obtained clearly show that the level-sets remain less than the radius in which the crack front was located. This means that the crack bottom has been correctly located by method GEOMETRIQUE.
