Hi,

I was trying to use as_run to call code_aster inside the Salome installation, I got the following error

/home/hemsxu/salome_meca/V2019.0.3_universal/tools/Code_aster_stable-v144_smeca/bin/aster: error while loading shared libraries: libgfortran.so.3: cannot open shared object file: No such file or directory
EXECUTION_CODE_ASTER_EXIT_16814=127
<INFO> Code_Aster run ended, diagnostic : <F>_ABNORMAL_ABORT

The setup files for the simulation works well since I already tested them salome_meca and then extracted it. I face this issue in code_aster as_run command; I searched for similar issues to find solutions, I already have the libgfortran.so.3 file in the lib folder, yet i have this error and I could not fix it. could someone please help me with this issue? 

Kind regards,
Hems

Hi Sukumar,

Thanks a lot. I followed the procedure again as per your suggestion. It worked!

But I have same message as Roger has about the Europlexus module. I decided to ignore it for now.


Thanks and regards,
Hems

Hi All,

I followed earlier reply on this topics and tried the procedure suggested by Mr.Sukumar. Unfortunately I still get the error.

I could not figure out how to fix it. Please suggest a solution.

Hi,

I am trying to understand the local axis of the section defined when using MACR CARA POUTRE to calculation sectional properties.

I understand that the X_local is along the beam direction, but it is not clear for me to identify Y_local and Z_local. Someone, please explain to me which direction is Y local

JP Aubry wrote:

in chapter-6 Understanding some details -pg. 62
• the local x axis lies along the beam;
• the local y axis lies by default in the global XOY plane;  (Not clear Y-local point towards the  X_global or Y_global when I draw the section in XOY plane to calculate the section properties using MACR_CARA_POUTRE)
• and the local z completes the trihedron.

When I tried to calculate a simple beam with rectangular cross-section 0.1*0.2 meter by defining it in the Global axis in a different direction to find the effect I realized it not making any difference. (Refer attached picture)

Please, someone, explain to me how to verify my beam orientation? Is it possible to visualize orientation? I have a model with beam elements in different directions to be assigned with H-sections. it is important for me to get it right. since it is difficult to verify with hand calculations like in simple beam cases.

Thanks and Regards,

Hello Everyone,

I am using the Salome-Meca windows version. I tried to click the reuse button in the Aster study module to run the calculation but I could not click it since it is disabled. only Run and Skip options are available. I would like to know from other users if this option is not available by default in the windows version ? or something wrong with my installation? I attached a picture for your reference.


Thanks and Regards,

#7 Re: Code_Aster usage » [SOLVED] get the displacement at each node in a table » 2020-01-14 17:15:23

Hi,

After a lot of trails, I got what I wanted by creating a table and then printing it

depl_Tab=CREA_TABLE(RESU=_F(GROUP_NO=[ENTER LIST OF NODES],
                    NOM_CHAM='DEPL',
                    NOM_CMP=('DZ', ),
                    RESULTAT=res),
                    TITRE='depl_Tab',
                    TYPE_TABLE='TABLE')

IMPR_TABLE(TABLE=depl_Tab,
             FORMAT='TABLEAU',
             UNITE=8,
             FIN_TABLE='',
             SEPARATEUR='|',
             COMMENTAIRE='#',
             COMM_PARA='',
             DEBUT_LIGNE='',
             FIN_LIGNE='\n',
             FORMAT_R='E12.5',
             IMPR_FONCTION='NON',

Hi Joan,

Thanks for the your reply. I already tried your suggestions but I get the displacement summation of the nodes I specify in one line. It is not giving the result I want. But it gives,

using nds_7 and nds_5 results
##ASTER 14.04.00 CONCEPT table CALCULE LE 08/01/2020 A 16:45:50 DE TYPE           
#TABLE_SDASTER                                                                   
INTITULE         RESU     NOM_CHAM         NUME_ORDRE   INST         DZ         
Disp             res      DEPL                        1  0.00000E+00 -5.33333E-07

similarly, I get sum of all nodes displacement if I add all the nodes in the list.


I need a table with columns of  NodeName-Displacement.

Hems

Hi,
I am new to code_aster.
I did a static analysis on a simply supported beam with a point load. I am interested in getting the displacement at each node of the beam in a table. I tried to use POST_RELEVE_T. I could get the result for one node. I could not understand how to obtain the displacement table for multiple nodes.

I attached the files herewith.

P.S: I grouped all nodes individually named nds_1,nds_2 ...nds_11to access them by name

Hi Everyone,

I am Hems. I am new to code_aster and I am trying to use it in my project to analyze a bridge structure.

I am interested in learning how to do Linear Static analysis and Dynamic analysis considering different load cases (Static and moving loads) using python scripting to study the bridge.

After exploring some options in commercial software, I decided to work with code_aster due to the possibilities it provides through scripting.

Looking forward to learning from this community.



Thanks and Regards,
