It is a square plate with a :math:`a\mathrm{=}10.` side and a :math:`t\mathrm{=}1` thickness.


Material properties
-----------------------

:math:`E\mathrm{=}1.`

:math:`\nu \mathrm{=}0.3`


Boundary conditions and loading
------------------------------------

The plate is embedded along side :math:`\mathit{AB}`.

We have 7 load cases for modeling A and 5 load cases for modeling B.

Each load case corresponds to the superposition of 2 loads that cancel each other out.

One of these loads applies to a GROUP_MA or GROUP_NO defined from a geometric criterion in DEFI_GROUP, the other, with the opposite sign, applies to the GROUP_MA or the GROUP_NO defined "in extension" (by hand).

Modeling A uses a "3D" model in shell DKT.

B modeling uses a "D_ PLAN" model in TRIA3.

The meshes are the same.
