pb with .med result file from aster code

Posted by guillaume niel at February 06. 2006

Hi,
I use salome with aster code and I have a problem with the post-processing. The computing with aster is ok and the result file .med is not empty, but when I try to open this file with salome (post processing module), there is a message which says that there are errors in the .med file.
I am using salome 2.2.8 and aster 8.2.
I don't know how to open the med file with a text editor to check anything.
What can I do now ?

Hello,

Med is binary format, if you open in text editor it gives you no readable info.

Is this file really big? If no I can check it in the latest development version.

Best regards,

Sergey.

Hi,
the result file weights about 150 ko.
How can I send it to you ?

    Hello,
    
    Same problem around here, Salome 2.2.8 and Aster 8.2 on a slackware-current. I have ripped the aster's IMPR_RESU block from CAElinux which is supposed to work, but it does not help.
    
    IMPR_RESU(MODELE=mecalin,
              FORMAT='MED',
              UNITE=80,
              RESU=(_F(MAILLAGE=maillage,
                       RESULTAT=Solution,
                       NOM_CHAM='DEPL',
                       NOM_CMP=('DX','DY','DZ',),),
                    _F(RESULTAT=Solution,
                       NOM_CHAM='EQUI_ELNO_SIGM',
                       NOM_CMP='VMIS',),),);
    
    --> this gives a .med without any tensor data for salome, but the "errors in the med file" still occurs. Maybe it's a version mismatch of the med library between salome (med 2.2.2) and aster (2.2.3). I may try to compile salome with a system-wide med library...

      Hi
      I had similar problem recently. It is caused by difference in HDF5 library. CA 8.2 is compiled with 1.6.4 and it is not compatibile with 1.4.3 version in Salome (binaries for RedHat). I tried to change it manually in salome and opening post processing files worked, but than saving stopped to work...
      I tried also to compile Salome with new library, but there was a problem with Python version.
      I think there will be easier to compile CA with earlier version of HDF5 library.

        Hello,
        You're right, the problem can be solved by a rebuild of aster with hdf 1.4.4 instead of 1.6.4. The process is quite simple, just unpack aster-full-src, download hdf5 1.4.4 and put it in aster-src-8.2.0/SRC. Replace all "1.6.4" occurences with "1.4.4", in products.py, et voilà. Don't forget to wipe your original /opt/aster or it will use any previously compiled libraries. Now Salome can read aster's result files
