6. D modeling#
6.1. Characteristics of modeling D#
The characteristics are identical to the reference solution. The modeling used is of the 3D_HM type. The mesh is shown on the, it consists of 80 HEXA20. In this modeling, \(\mathit{LX}=5m\) and \({L}_{d}=\mathrm{2,6}m\), the discontinuity is thus not in accordance with the mesh. The central HEXA20 are crossed by the crack.

6.2. Tested sizes and results#
In the left column, the pressure of pore PRE1 is tested at time \(t=\mathrm{0,0001}s\) at various heights in the column. The results obtained are similar to those obtained for classical 3D_HM modeling but slightly less accurate than those obtained with conventional 3D_ HMD modeling at the top of the column.

The results obtained for the pore pressure at the final instant \(t=\mathrm{0.0001s}\) are shown on the. A clear discontinuity in the pore pressure is clearly observed on both sides of the crack. The HEXA20centraux are subdivided into under TETRA HM_XFEM.

In the right column, the pressure of pore PRE1 is tested at time \(t=\mathrm{0,0001}s\) at various heights in the column. The results obtained are similar to those obtained for classical 3D_HM modeling but slightly less accurate than those obtained with conventional 3D_ HMD modeling at the top of the column.
