3. Modeling A#
3.1. Characteristics of modeling A#
The characteristics are identical to the reference solution. The modeling used is of the D_ PLAN_HM type. The mesh is shown on the. In this modeling, \(\mathit{LX}=\mathrm{4m}\) and \({L}_{d}=2m\), the discontinuity is thus in accordance with the mesh.
Figure 3.1-12D mesh modeling A
3.2. Tested sizes and results#
In the left column, the pore pressure PRE1et and the stress SIYY at the final instant \(t=\mathrm{250s}\) are tested at various heights in the column. The results obtained are similar to those obtained for classical D_ PLAN_HM modeling but slightly less accurate than those obtained with conventional D_ PLAN_HMD modeling at the top of the column.
