Innovations between 7.3 and 7.4
1.1
Modifications of the environment
1.1.1 Med
Code_Aster is pressed now on library MED 2.2. For reading files with the format med
2.1.5, they should be converted with the tool med_import (there are not tools in the opposite direction).
1.1.2 Lobster
Following the change of version of med, lobster also evolved/moved to support the same level
of library. lobster 7.1 also brings other innovations (cf [U7.03.xx]).
1.2 News
commands
1.2.1 CREA_TABLE
This command makes it possible to create a table starting from a function or several lists of entireties, of
realities or of character strings. One can create a full table or with holes by indicating the lines
that one wishes to inform.
1.2.2 DEFI_COMPOR
This command makes it possible to define a single-crystal or polycrystalline behavior.
1.2.3 DEFI_PART_FETI
This command makes it possible to create a partitioning in under-fields for a resolution by
Feti method.
1.2.4 IMPR_FONCTION
This new command replaces IMPR_COURBE, and it treats only the functions (from where it
renaming), tables being treated by IMPR_TABLE (cf [7.3.13]).
1.2.5 MACR_ECLA_PG
This macro-command replace options ECLA_PG of two commands CREA_MAILLAGE and
CREA_RESU. Coherence between the two commands is thus ensured.
1.2.6 MODI_MODELE_XFEM
This command makes it possible to create finite elements with ddl nouveau riches necessary to the method
XFEM.
1.3 Commands
reabsorbed
1.3.1 DEFI_VALEUR
Contents of the Python objects being backed up (in the file pick.1) “at side” of the Aster base
(file glob.1), it is not necessary any more to have a specific command to define a parameter.
For example (see also [U3.01.0x]):
deuxpi = 2.* pi
1.3.2 IMPR_COURBE
Replaced by IMPR_FONCTION (cf [7.3.13]).
1.3.3 POST_GOUJ 2nd
This command had not been reabsorbed at the same time as the associated macros
MACR_GOUJ 2E_MAIL/CALC. The method for calculation is preserved in the case-tests zzzz120a
and zzzz120b (cf [7.2.14]).

1.4
Modifications common to several commands
1.4.1 Key words
FICHIER and UNITE
According to the type of command, one was to use is UNITE (reading commands) where one was awaited
logical number of unit, is FICHIER (commands of postprocessing) behind which one waited not
not a file name but a “label” (ddname) which was associated a logical unit by
defect or affected via command DEFI_FICHIER (ex-DEFUFI).
The concept of label disappears; the commands function all with UNITE and, those which know
to use a true file name also key word FICHIER accepts.
The risk of confusion is reduced: one provides to UNITE the logical unit well informed in astk and to
FICHIER a file name complete Unix (see also the use of REPE_IN/REPE_OUT in
documentation of astk [U1.04.00]).
1.4.2 Commands of postprocessing CALC_ELEM, CALC_NO, CALC_G_LOCAL_T,
CALC_G_THETA_T, POST_ELEM
MODELE, CHAM_MATER, CARA_ELEM, EXCIT become optional:
· The structure of data result (exit of STAT_NON_LINE, THER_LINEAIRE…) keep in
memory these 4 parameters, it thus becomes optional to provide them to these operators post-
processing. One can however inform these key words in certain particular cases; one
check whereas they are the same ones which was used for calculation, if it is not the case, one emits
an alarm or one stops in error (case of the MODELE) (cf [7.3.7], [7.3.24]).
1.5 Commands
modified
1.5.1 AFFE_CARA_ELEM
ANGL_L, POUR_CENT_L, POUR_CENT_T removed, famous SECTION_L in SECTION:
· These key words do not have any more interest since the introduction of new elements of grid
membrane which makes it possible to model the grids of reinforcement in a given direction, and
who are usable jointly with a modeling 3D of the concrete. In the same way elements
roast (usable with “hull” work from now on in only one direction. Orientation
reinforcements is defined under ANGL_REP (cf [7.3.10]).
Modified POUTRE/VARI_SECT:
· To guide the user among the possible choices, one chooses a value now for
SECTION, then for VARI_SECT (new choice: CONSTANT by defect) what allows
to limit the list of possible for CARA (cf [7.3.23]).
PREC_AIRE, PREC_INERTIE new:
· One checks the coherence of the information (surface and inertia of the multifibre beams) provided under
key words POUTRE and AFFE_SECT with the precision indicated by these key words (cf [7.3.28]).
1.5.2 AFFE_CHAR_MECA/AFFE_CHAR_MECA_F
New FORMULATION:
· At the time of the resolution of a problem of contact with the method continues, one has the choice enters
a formulation in displacement (value DEPL) or of speed (value VITE, adapted well
numerically with the processing of the shocks) (cf [7.3.18]).
TOLE_PROJ replaced by TOLE_PROJ_EXT, new TOLE_PROJ_INT:
· In the case of symmetrical pairing MAIT_ESCL_SYME, it is necessary to lay out
of a tolerance of projection for the detection of the null pivots (cf [7.3.23]).
New ITER_MULT_MAXI:
· ITER_MULT_MAXI multiplied by the number of nodes slaves gives the maximum number
iterations of contact (cf [7.3.23]).

1.5.20 IMPR_RESU
FICHIER, FORMAT moved:
· These key words are moved out of the key word factor RESU so that one cannot any more
to use only one IMPR_RESU to write in two different files (because the files were
often incomplete) (cf [7.3.14]).
1.5.21 IMPR_TABLE
The command was completely rewritten (cf [7.3.27], [7.3.29]).
Modified FORMAT:

Innovations between 7.2 and 7.3
2.1 News
commands
2.1.1 MACR_FIABILITE
This macro-command calculates the probability that a physical variable (displacement, forced,…)
exceed a threshold defined by the user according to a certain number of parameters which will have been
defined as sensitive by the user. These significant parameters can be the Young modulus,
Poisson's ratio, a pressure, etc
The macro-command calls upon the software MEFISTO which is external in Code_Aster, and which puts in
work method FORM. (cf [7.2.11).
2.1.2 STANLEY
Stanley, tool for interactive postprocessing, was already present in version 7; this macro-command
simplify its call since one now launches it like an ordinary command. (cf [7.2.25]).
2.1.3 TEST_FICHIER
This macro-command makes it possible to test nonthe regression of the commands which produce
files, to the attention of the developers (cf [7.2.25).
2.2 Commands
reabsorbed
2.2.1 FACT_INTE_SPEC
This command was amalgamated with GENE_FONC_ALEA (cf [7.2.3]).
2.2.2 MACR_GOUJ 2e_MAIL and MACR_GOUJ 2e_CALC
These two macro-commands are reabsorbed. The method for calculation is preserved in
command files zzzz120a and zzzz120b which validated these functionalities. (cf [7.2.14]).

components; the pressure of dissolved air is connected to the pressure of dry air by the law of Henry
(cf [7.2.7]).
GRILL_MEMBRANE new modeling:
· It is about a new element of tablecloths of reinforcement which works only out of membrane, not of
ddl of rotation (cf [7.2.21]).

restricted according to the type of loading (cf [7.2.5]).
CRITERE=' DOMM_MAXI', PROJECTION, DELTA_OSCI new:
· These key words are associated the new criterion adapted to the nonperiodic loadings; it
acts of a criterion with variable amplitude based on a critical level selected according to
induced maximum damage (cf [7.2.5]).
CRITERE=' DANG_VAN__MODI_AC'/new “DANG_VAN_MODI_AV”:
· It is about a criterion with variable amplitude based on a critical level selected from
maximum damage. This criterion which is adapted if the loading is not periodical
is an evolution of the criterion of original DANG VAN. “AC” for constant amplitude, “AV” for
variable amplitude (cf [7.2.11]).
2.3.7 CALC_G_THETA_T
New type for the field:
· One can now provide a field of the cham_no_depl_r type (and to build it made-to-order!)
in the place of that provided by CALC_THETA (cf [7.2.8]).
2.3.8 CALC_NO
GROUP_MA_RESU, GROUP_NO_RESU, MAILLE_RESU, NOEU_RESU new:
