Modeling A
==============


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

The calculation is done in two-dimensional static mechanics, in plane deformation.


Characteristics of the mesh
----------------------------


.. _OLE_LINK1:

Slices :math:`A` and :math:`B` are meshed with 8 triangles TRIA3. They form the group of elements named 'TRIA'. Slices :math:`C` and :math:`D` are meshed with 4 quadrants QUAD4. They form the group of elements named 'QUAD'.

The 4 triangles in slice :math:`B` and the 2 quadrangles in slice :math:`C` are combined in group 'MILIEU'.

The outer border segments are meshed with 12 SEG2 segments. They are grouped into 4 groups named :math:`\text{BORD\_INF}`, :math:`\text{BORD\_DRO}`,, :math:`\text{BORD\_SUP}` and :math:`\text{BORD\_GAU}`.

Features tested
-----------------------

This case tests the various options for writing in 'MED' format via the IMPR_RESU command. To do this, we calculate various options complementary to the displacement alone and we create a magnitude field equivalent to the displacement field at the nodes. The impressions are successively as follows:


* the displacement field at the nodes and the stress field at the Gauss points, expressed over the entire mesh. This triggers the creation of a profile for the move because it is not defined everywhere: the three nodes :math:`M`, :math:`N` and :math:`O` do not have a value,


* the magnitude field. It uses the same profile as the standard result displacement field,


* the components' SIXY 'and' SIYY 'of the constraint field at the nodes by element' SIGM_ELNO ',


* the error indicator 'ERRE_ELGA_NORE' on the stitches in group :math:`\mathit{MILIEU}`. This triggers the creation of two profiles because the values written are not written on all meshes. The first profile concerns the 4 triangles out of the 8 in total; the second concerns the 2 quadrangles out of the 4 in the total.

The rereading from the 'MED' format is that of the displacement field at the nodes contained in the quantity field.
