4. B modeling#
4.1. Characteristics of modeling#
This is a 3D_HM modeling using quadratic HM- XFEM elements.
4.2. Characteristics of the mesh#
The block on which the modeling is performed is divided into 49 QUAD8.
4.3. Tested sizes and results#
We test the value of the vertical movements for the nodes \(A\), \(A\text{'}\),,, \(B\) and \(B\text{'}\) which are located on the interface as well as the value of the pressure of the fluid in the interface at these 4 points. These values are summarized in the table below:

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