3. Modeling A#
3.1. Characteristics of modeling#
The calculation is done in two-dimensional static mechanics, in plane deformation.
3.2. Characteristics of the mesh#
Slices \(A\) and \(B\) are meshed with 8 triangles TRIA3. They form the group of elements named “TRIA”. Slices \(C\) and \(D\) are meshed with 4 quadrants QUAD4. They form the group of elements named “QUAD”.
The 4 triangles in slice \(B\) and the 2 quadrangles in slice \(C\) are combined in group “MILIEU”.
The outer border segments are meshed with 12 SEG2 segments. They are grouped into 4 groups named \(\text{BORD\_INF}\), \(\text{BORD\_DRO}\),, \(\text{BORD\_SUP}\) and \(\text{BORD\_GAU}\).

3.3. 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 \(M\), \(N\) and \(O\) 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 \(\mathit{MILIEU}\). 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.
