B modeling
--------------

Characteristics of modeling
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Modeling B re-uses the interstitial pressure field from modeling A,
but apply algorithm SRM to the entire model with the Drucker-Prager law.
In addition, the law of linear variation of the increment of the safety factor is used,
with "INCR_INIT = 0.05"," RESI_MAXI = 0.01", and "= 0.01", and" ITER_RAFF_LINE = 1".

Since the difference between the initial increment and the maximum residue is large, this configuration
convergence parameters require the algorithm to converge after refining the increment.

Tested sizes and results
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The safety factor and the maximum total displacement are tested at each iteration SRM.

The reference values are shown in :ref:`Tableau 4<table4_v101135>`.
