#1 Code_Aster usage » How does the AsterStudy component work? » 2019-12-12 19:12:46

If you dump a case it comes out as a python script, in that script amongst other components there is the Asterstudy component, which is...empty...
Should it be empty? How can i populate it so to add a case always as a python script or save them as scripts??

I searched and found a similar topic here forum2/viewtopic.php?id=19764 . Is there a way around this bug ? I am using Salome Meca 2018. Does it change in the 2019 version??

#3 Re: Code_Aster development » Is there any plan to change code_aster to English? » 2019-12-06 23:00:19

The errors would be a nice start ! Also some commands for example the interactive of CALC_ESSAI

#4 Re: Code_Aster usage » How to import a .uff file with modal information in code_aster? » 2019-12-05 18:24:51

The error was given due to the Dataset 2412 contained in the .uff file . By deleting this dataset it becomes possible to read the information contained in the file. Now on to the second part of the problem with LIRE_RESU.!!

This is also discussed in the following threads :

Hello,

having a similar problem i found these threads quite helpfull : /viewtopic.php?id=21214 , forum2/viewtopic.php?id=24578 .
Maybe the second one is closer to what you are looking for.

You have to give it more time to perform the calculation.

#8 Re: Code_Aster usage » Material propetries on nodes and extraction » 2019-12-03 14:42:56

Hello all,

by using the series of commands found in this thread : /viewtopic.php?id=21214 , i have successfully assigned the material properties to the nodes of my model. Now i would like to know if there is a way to print the informations. I can print them using IMPR_RESU command but i would like to know if there are alternatives? Like IMPR_TABLE or by use of python. I leave here the series that i used just in case someone needs it too:

CHAMGEO = CREA_CHAMP(MAILLAGE=mesh,
                     NOM_CHAM='GEOMETRIE',
                     OPERATION='EXTR',
                     TYPE_CHAM='NOEU_GEOM_R')

CHFONC = CREA_CHAMP(AFFE=_F(GROUP_NO=('GrTorre_Nodes', ),
                            NOM_CMP=('X1', ),
                            VALE_F=(YOUNG_Z, )),
                    MAILLAGE=mesh,
                    OPERATION='AFFE',
                    TYPE_CHAM='NOEU_NEUT_F')

CHYOUNG = CREA_CHAMP(CHAM_F=CHFONC,
                     CHAM_PARA=(CHAMGEO, ),
                     OPERATION='EVAL',
                     TYPE_CHAM='NOEU_NEUT_R')

Hello,

i am making reference to this thread https://ww w.code-aster.org/forum2/viewtopic.php?id=17518 . I have followed the suggestions of RichardS and have assigned the material properties in the field. How can i print all the nodes with said field tho? I have checked in the documentation but no mention of creating an example of a table containing the Node number or / element number and the assigned property exists. Do you have any suggestions on how to visualize?

#10 Re: Code_Aster usage » Mapping of material properties » 2019-11-22 12:17:03

Hello,

from the date of this thread seems a little old but due to the fact that the arguments implementation interests me and don't want to recreate a thread i post here. Have you had any kind of advancement regarding the material properties mapping procedure?

Thank you!

Is there a way to do this kind of operation with the commands available ?

Thank you!

#12 Re: Code_Aster usage » Number of digits of modes » 2019-11-21 13:45:51

It is not exactly a Modal Analysis question the one i have but i would like to know if it is possible to access the number of  elements and the values of the Elastic Modulus each one has. Would i have to assign a group with the elements i want to access and then through the .comm file enter into the AFFE_MATERIAU command?

#14 Re: Code_Aster usage » Code_Aster and Openturns » 2019-11-20 11:40:36

Within the Code_Aster environment it is possible to perform and analysis to calculate the clean modes.
That response can be seen as NUME_ORDRE and FREQ, correct? I define with the RECU_TABLE command from the analysis part of CALC_MODES, the parameters that i want to imprint in a table with IMPR_TABLE command. The openturns documentation and videos that are available suggest to print the parameters of out as NUMPY ( .npy) files so that those can be read and imported along with the  defined variables in the OpenTURNS environment so to continue on with the sensitivity or probabilistic analysis of the model. Am i misinterpreting something because when i make this kind of operation i cannot seem to get the frequencies of the model i am studying in OpenTURNS.

Thank you very much.

#17 Re: Code_Aster usage » How to export node coordinate? » 2019-11-18 15:30:03

I think you should look into the chapters 18 and 19 of Jean pierre aubry's book you can find it in framabooks site. I think it gives an example of something quite close to what you are trying to do.

Thank you very much for the code and the reference provided.
I have read and still reading  Jean Pierre's book but in a bible like that things are missed.
A question if i may. Since it is possible to extract node coordinates, is it also possible to extract the connecting lines coordinates too?

Thank you in advance!

Hello all,

i would like to ask if it is possible to export in a python script inside the .comm file the nodes or nodes coordinates.
Where should i search for this particular operation?Through the documentation i might have missed something, are there
any suggestions?

Thank you.

Hello all,

i would like to ask how should one model a wooden structure in code aster.
Are 3D elements a good choice or should one go with plate elements and vary the thickness accordingly?
Also for costitutive laws which ones are the best to use?

Thank you!

Hello,

i was wondering, how the CALC_MODES command, calculates the nodal displacement and how it handles it in the 3D medium?
Is it possible through Aster to calculate externally,via python script, the eigenvalues and eigenvectors and input them in code_aster?
