3. Modeling A

3.1. Characteristics of modeling

This is a D_ PLAN_HM modeling using quadratic HM- XFEM elements.

3.2. Characteristics of the mesh

The block on which the modeling is performed is divided into 625 QUAD8.

3.3. Tested sizes and results

We test the value of the vertical displacements for the nodes \(A\) and \(B\) which are located on the interface as well as the value of the pressure of the fluid in the interface at these 2 points. These values are summarized in the table below:

Quantities tested	Reference type	Reference value
DY (node A below)	“NON_REGRESSION”	-8.731819099E-5 m
DY (node A above)	“NON_REGRESSION”	8.731819098.E-5 m
DY (node B below)	“NON_REGRESSION”	-4.62904976E-5 m	-4.62904976E-5 m
DY (node B above)	“NON_REGRESSION”	4.62904976E-5 m
PRE_FL1 (node A)	“NON_REGRESSION”	816304Pa
PRE_FL1 (node B)	“NON_REGRESSION”	712838Pa

3.4. notes

The pore pressure field and the amplified deformation (X1000) (Figure) were also post-treated using SALOME.
