4. B modeling#
4.1. Characteristics of modeling#
Method GEOMETRIQUE is used by PROPA_FISS to update the crack position.
4.2. Characteristics of the mesh#
The same mesh as that used for modeling A. is used.
4.3. Tested sizes and results#
We test the values of \({K}_{I}\) at each propagation step.

The mechanical residual error indicator “ERME_ELEM” is also tested on the last propagation step (in non-regression only) in order to validate the use of this indicator on 2D models with rotations.
