B modeling
==============


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

Modeling B uses a behavior model for the linear embankment, the calculation of the initial stresses using the operator MECA_STATIQUE and the dynamic calculation using DYNA_VIBRA. The evaluation of the safety factor is carried out by the macro command POST_NEWMARK directly by providing the radius and coordinates of the sliding circle.

We activate the option to check the mass of the sliding zone, with a relative error RESI_RELA of 2%.


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

The value of the seismic coefficient :math:`{k}_{y}` obtained by the macro-command is tested by comparing it to the value estimated by the GeoSlope software and used as input to the modeling A.
