Modeling E
==============


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

The E modeling uses the equivalent linear model implemented under *Code_Aster* in Macro-command DEFI_SOL_EQUI [:ref:`U4.90.21 <U4.90.21>`] with a loading in the free field and a single-support approach by considering a 1D — 1 component hypothesis, with the consideration of water pressures in a simplified manner via the Byrne model. E-modeling adopts the boundary conditions and loading defined in the reference problem.


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

The results of a 1D — 1 component modeling with the macro control are taken for reference at two levels of the soil column, points A (inside layer 1) and B (inside layer 4)
