FORMA06 - TP beam of the formation post
processing

Summary:

The objective of this T.P. is to use the possibilities of POST-TRAITEMENT available in Code_Aster in
the case of a modeling of the type POUTRES.

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 grid 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 formats RESULTAT, 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.
