Please post your .mess file (if one is created) or post a screenshot of the error, otherwise it's impossible for us to help you

Hello,
there seems to bee a mismatch between the version of EFICAS which was used to create the command file
and the Code-Aster version used to run the simulation.

CALC_NO and CALC_ELEM were replaced by CALC_CHAMP since 11.3 I think and are no longer valid in newer versions.

Deleting them and replacing by

RESU=CALC_CHAMP(reuse =RESU,
               MODELE=MODE,
               CHAM_MATER=MATE,
               RESULTAT=RESU,
               OPTION=('SIGM_NOEU','SIEQ_NOEU',),
               EXCIT=_F(CHARGE=CHAR,),);

should do the job.

But generally there could be also a lot of other syntax changes so I would advise you to use a newer eficas version
(or just change the Code-Aster version setting to the version you are using for solving).

Best regards,
Richard

Thank you,

I replaced it, but still have a failure when simulating.

I checked code - looks like other in command file should be in accordance with Aster version.
I tried to follow the logic of problem - may be smth wrong with "fix" group?

Sorry,
there were some more errors in the CALC_NO/CALC_ELEM commands.
This should do the trick:

RESU=CALC_CHAMP(reuse =RESU,
               MODELE=MODE,
               CHAM_MATER=MATE,
               RESULTAT=RESU,
               CONTRAINTE=('SIGM_NOEU',),
	       CRITERES=('SIEQ_NOEU',),
               EXCIT=_F(CHARGE=CHAR,),);

Thank you,

looks like this part is OK,
but now I have problem with density definition "RHO"
www.dropbox.com/s/y3h9zgvh4pgfo84/rot3.comm?dl=0
www.dropbox.com/s/8c3aote5ptyw7hy/nrot3_case1.mess?dl=0

I checked in Aster operators file:
www.code-aster.org/V2/doc/v10/en/man_u/u4/u4.43.01.pdf
RHO - should be OK as well as Modulus Young E and Poisson's ratio NU.

What the reason of this mistake could be?
