C modeling
==============


Characteristics of C modeling
-------------------------------------

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 64 HEXA20. In this modeling, :math:`\mathit{LX}=\mathrm{4m}` and :math:`{L}_{d}=2m`, the discontinuity is thus in accordance with the mesh.

Tested sizes and results
------------------------------

In the left column, the pressure of pore PRE1 is tested at time :math:`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 :math:`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 :math:`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.
