Advanced Simulations Examples with CAE 2009?

I'm curious to know if the examples posted here

www.caelinux.com/CMS/index.php?option=co...;id=25&Itemid=40

need to be updated to match the syntax for Code Aster 9.4. I downloaded one of them and it was throwing some error messages.

Claus, I nominate you to double check my work when I post up new refreshed examples for 2009! Seriously, I'm going to take a look at the contact ones this weekend and see what I can figure out...

I updated the assembly tutorial from the link above. It was pretty easy. I made two changes

1.

Remove MODELE=FEMQuad,); from the end of the ORIE_PEAU_3D statement. Looks like Code Aster 9.4 syntax eliminated the need to explicitly indicate the model when changing the normals to point outward from the surface

2.

FIN(FORMAT_HDF='OUI',); was causing Code Aster to throw an error, 136 if I remember right. I've never used this output option so I changed it to FIN(); and everything worked.

I checked the assemblyres.med file that came with the original download and the one generated with CAELinux 2009 and everything looks the same in the results.

The updated comm file is attached

ok, I thought I attached the file but I can't see it... I'm going to try it again.. do I need to do anything special other than use the &quot;Select file to attach&quot; below the text box in the new post page?

Updated Contact Example

Changes:

1. Removed TEMP_CALCULEE assignment

temp=AFFE_CHAR_MECA(MODELE=FEMQuad,
TEMP_CALCULEE=tempf,);

this has been replaced with

Mat=AFFE_MATERIAU(MAILLAGE=MeshQuad,
MODELE=FEMQuad,
AFFE=(_F(GROUP_MA='F3',
MATER=Steel,),
_F(GROUP_MA='F4',
MATER=Alu,),),
AFFE_VARC=_F(TOUT='OUI',
NOM_VARC='TEMP',
CHAMP_GD=tempf,
VALE_REF=0.0,),);

where AFFE_VARC is the new way to assign a temperature field. It is now handled when assigning a material to the mesh.

2. Changed the CONTACT definition

removed RECHERCHE='NOEUD_BOUCLE' because this syntax is no longer valid. It is now the default option.

removed PROJECTION='QUADRATIQUE' I'm not sure what this does but it was causing a syntax error and the simulation results without it look OK.

removed NB_REAC_MAXI=10 ... again I'm not sure exactly what impact this has

3. Added SOLVEUR=_F(SYME='OUI') to STAT_NON_LINE because I was getting an alarm for a symmetrical matrix even though it seem as if everything should solve. This did the trick and the results look the same as the pervious result med file supplied with the original tutorial

4. Changed FIN(FORMAT_HDF='OUI') to just FIN();
