FORMA08 - Work practice Postprocessing 3D
Summary:
This test corresponds to the TP 3D of the formation to the post processing using Code_Aster (postprocessing of one
calculation of piping bent in 3D).
This TP is the continuation of the TP of the basic training Aster included in the case test forma01c describes in
documentation of validation [V7.15.100].
It is about a bent piping made up of a linear elastic material. One considers only one case of
loading (force applied at the end of the elbow).
In this T.P, one is interested in the operators of post following processing:
·
Operators allowing to define groups of entities of the mesh type (
DEFI_GROUP
for
definition and the handling of groups of nodes and meshs,
MODI_MAILLAGE
for
reorientation of the elements of face subjected to a pressure).
·
Total operators allowing to enrich the concepts results (
CALC_ELEM
for the calculation of
fields with the elements,
CALC_NO
for the calculation of the fields to the nodes).
·
Impressions (
IMPR_RESU
for the impression of the results to the formats
RESULT
,
IDEAS
,
GIBI
)
·
Localized examinations (
POST_RELEVE_T
for the statement of values on lines or groups
nodes and calculation of derived quantities).
·
Layout of curve (
IMPR_COURBE
for the visualization of the evolution of a size according to
time or of space).

Boundary conditions and loadings
A condition of embedding is applied to section A,
The loading applied is a constant force FY = 100.000 NR directed according to the axis Y and applied to
the section B.
1.4
Reference solution
The reference solution is obtained numerically, it thus acts of a test of nonregression.

5 Synthesis
This case test, redundant as regards calculation with modeling C of the case test FORMA01, has for
objective to ensure that the command files of the TP of the formation “post processing” follow them
evolutions of syntax of the code.
