Innovations and amendments of version 7
Summary:
The object of this document is to offer a global vision of the amendments of syntax and new possibilities
controls of Code_Aster occurred between each version since version 7.0.
Index A of this document thus gives a report on the changes introduced since version 7.3 of April 2004 and
valid for version 7.4 of December 2004.
For more precise details, one will consult the documentation of the controls and the file
histor
corresponding under-version (e.g.: [7.3.12], section Development of the site
www.code-aster.org
).
The impacted controls are listed alphabetically.

Innovations between 7.3 and 7.4
1.1
Amendments 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 bring other innovations (cf [U7.03.xx]).
1.2 News
controls
1.2.1
CREA_TABLE
This control 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 control makes it possible to define a single-crystal or polycrystalline behavior.
1.2.3
DEFI_PART_FETI
This control makes it possible to create a partitioning in under-fields for a resolution by
Feti method.
1.2.4
IMPR_FONCTION
This new control 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-control replace the options
ECLA_PG
of the two controls
CREA_MAILLAGE
and
CREA_RESU
. Coherence between the two controls is thus ensured.
1.2.6
MODI_MODELE_XFEM
This control makes it possible to create finite elements with ddl nouveau riches necessary to the method
XFEM.
1.3 Controls
reabsorbed
1.3.1
DEFI_VALEUR
Contents of the Python objects being backed up (in the file
pick.1
) “at side” of the base Aster
(file
glob.1
), it is not necessary any more to have a specific control 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 control 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
Amendments common to several controls
1.4.1 Key words
FILE
and
UNIT
According to the type of control, one was to use is
UNIT
(reading commands) where one was awaited
logical number of unit, is
FILE
(controls 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 the control
DEFI_FICHIER
(ex-
DEFUFI
).
The concept of label disappears; the controls function all with
UNIT
and, those which know
to use a true file name also the key word accepts
FILE
.
The risk of confusion is reduced: one provides to
UNIT
the logical unit well informed in astk and with
FILE
a file name complete Unix (see also the use of
REPE_IN/REPE_OUT
in
documentation of astk [U1.04.00]).
1.4.2 Controls of postprocessing
CALC_ELEM, CALC_NO, CALC_G_LOCAL_T,
CALC_G_THETA_T, POST_ELEM
MODEL, 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
MODEL
) (cf [7.3.7], [7.3.24]).
1.5 Controls
modified
1.5.1
AFFE_CARA_ELEM
ANGL_L, POUR_CENT_L, POUR_CENT_T
removed,
SECTION_L
famous 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 modelize 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]).
BEAM/VARI_SECT
modified:
·
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
BEAM
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
FORMULATION
new:
·
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
QUICKLY
, adapted well
numerically with the processing of the shocks) (cf [7.3.18]).
TOLE_PROJ
replaced by
TOLE_PROJ_EXT, TOLE_PROJ_INT
new:
·
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]).
ITER_MULT_MAXI
new:
·
ITER_MULT_MAXI
multiplied by the number of nodes slaves gives the maximum number
iterations of contact (cf [7.3.23]).

Innovations between 7.2 and 7.3
2.1 News
controls
2.1.1
MACR_FIABILITE
This macro-control 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-control 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-control
simplify its call since one now launches it like an ordinary control. (cf [7.2.25]).
2.1.3
TEST_FICHIER
This macro-control makes it possible to test nonthe regression of the controls which produce
files, to the attention of the developers (cf [7.2.25).
2.2 Controls
reabsorbed
2.2.1
FACT_INTE_SPEC
This control 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-controls are reabsorbed. The method for calculation is preserved in
command files
zzzz120a
and
zzzz120b
who validated these functionalities. (cf [7.2.14]).
2.3 Controls
modified
2.3.1
AFFE_CARA_ELEM
RIGI_MISS_3D
new:

frequency of extraction given (cf [7.2.2]).
2.3.2
AFFE_MODELE
* _HH 2D
new modelings:
·
These modelings make it possible to take into account two phases in both
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]).

changed: the user must calculate the stress field in a point thickness
