B modeling ============== Characteristics of B modeling ------------------------------------- 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, :math:`\mathit{LX}=\mathrm{5m}` and :math:`{L}_{d}=\mathrm{2,6}m`, the discontinuity is thus not in accordance with the mesh, it crosses QUAD8. .. image:: images/100000000000027A00000335A257A47087CA5CD7.png :width: 3.0327in :height: 3.8437in .. _RefImage_100000000000027A00000335A257A47087CA5CD7.png: Figure 4.1-12D mesh modeling B Tested sizes and results ------------------------------ In the left column, the pore pressure PRE1et and the stress SIYY at the final instant :math:`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. .. csv-table:: "**Value tested**", "**Height (m)**", "**Height (m)**", "**Instant (s)**", "**Type**", "**Reference**" "Displacement PRE1 ", "8.75", "0.
