FORMA06 - TP beam of the formation post
processing
Summary:
The objective of this T.P. is to use the possibilities of POSTPROCESSING available in Code_Aster in
the case of a modeling of the BEAMS type.
It is about a gantry with side connections made up of a linear elastic material. In this T.P, one is interested
with the following operators of postprocessing:
·
operators allowing to define groups of entities of the mesh type:
DEFI_GROUP
(definition and
handling of groups of nodes and meshs),
·
total operators allowing to enrich the concepts results:
CALC_ELEM
for the calculation of
fields with the elements and
CALC_NO
for the calculation of the fields to the nodes,
·
impressions:
IMPR_RESU
(impression of the results to the formats
RESULT
,
IDEAS
,
GIBI
),
·
localized examinations:
POST_RELEVE_T
to raise of values on lines and calculation of
derived quantity,
·
layout of curve:
IMPR_COURBE
to visualize the evolution of a size according to space.

Summary of the results
The results obtained with Code_Aster are in concord with the reference solution.
The recovery in this case test of the command file of the TP on the post processing of the beams allows
to make sure that this file remains in agreement with the evolutions of syntax of the code.
