Random vibration

razvan.curtean

Hello

I'm trying to do an random vibration analysis and I have a problem with reading the stress values accordingly with U4.63.22

♦ NOM_CHAM = / 'DEPL' / 'VITE' / 'ACCE' / 'EFGE_ELNO' / 'SIPO_ELNO' / 'SIGM_ELNO' / 'FORC_NODA', ♦ NOM_CMP = / 'DX' / 'DY' / 'DZ' / 'SMFY'

/ 'SMFZ',.

But I get the folowing error.

!---------------------------------------------------------------------! ! <F> <ALGORITH10_72> ! ! ! ! il faut définir une liste de mailles pour post-traiter un CHAM_ELEM ! ! ! ! ! ! Cette erreur est fatale. Le code s'arrete. !

!---------------------------------------------------------------------!.

Attachet you can find my mess file.

I can read statistical values for displacement but I don't know how to do this for stress.

Do you have a solution or an example?

Thanks

I just want to ask again. If somebody can help me with reading the statistical stress values, would be very helpfull to me.

Thanks in advance

Now trying to read the stress I get a new error:

!-------------------------------------------------------! ! <EXCEPTION> <SOUSTRUC_59> ! ! ! ! le noeud : N216 n'appartient pas a la maille : M398 ! !-------------------------------------------------------!

.

I really don't understand this because I have selected node 216 from the mail 398. Do you know what is wrong?

Here you can find my files.

Thanks

Hello,

Finally I have chosen correct the Maille but I got:

!-----------------------------------------------------------------------! ! <EXCEPTION> <ALGORITH14_64> ! ! ! ! il manque le mode statique nom_cham SIGM_ELNO_DEPL pour le mode 25 ! !-----------------------------------------------------------------------!

.

I choose for the calculation 1-1500 Hz and MODE_ITER_SIMULT found 6 modes. Does have sense the error?

I will appreciate any hint or idea.

Thanks

Hi!

Sorry for necromancing an old thread, but I tried to port your example into aster 12.2, and I still have similar problems.

the error message shown above could be circumvented by compting SIEF_ELNO for STAT with CALC_CHAMP.

Nevertheless I got a new error:

!-----------------------------------------------------------------------------------! ! <EXCEPTION> <JEVEUX_26> ! ! ! ! Objet JEVEUX inexistant dans les bases ouvertes : >STAT .017.000024.VALE< ! ! l'objet n'a pas été créé ou il a été détruit !

!-----------------------------------------------------------------------------------!

I also reported the bug (at least I suppose it is one) on bittbucket: https://bitbucket.org/code_aster/codeaster-src/issue/43/very-strange-error-message-with
