Salome 3.2.1 & Code-Aster

Hello all,

I am trying to use the new Salome 3.2.1 with Code-Aster 8.2.0 and am running into some problems. I have some very basic questions:

1. Is Salome 3.2.1 compatible with ASTER 8.2.0 07/12/2005?
2. Should one be exporting the Salome mesh for Code-Aster in MED format 2.1 or 2.2?

Thanks
JMB

Hi JMB

So far I think they are compatible, but I am not 100% sure. I think you should export in 2.2 format.

See my question below. Any idea?

Dear all,

First of all, thanks to the code-aster group for the wonderful software made available to the community.

Now here is my problem:

I have just installed both Salome 3.2.1 and Code-Aster 8.3. Code-Aster compilation/installation was almost perfect. When i try to run a job with ASTK, the job starts but ends almost immediately. To see what happened I open a console cd to /home/myhomedir/flasheur and try to run the job manually. For example
./barragem.u10833
Here is the message it produces:

---

It seems that I have a problem of permissions. If I su to root, the job runs OK.

Somebody can help?

Yes,
I am not 100% sure, but this can be a problem of access permission in /opt/aster/ASTK directory. Try to chmod ASTK/ASTK_SERV directory to allow rw access to your user.

PS: concerning ASTER 8.2 + SALOME, maybe this could be solved by recompiling aster 8.2 with the med libraries of Salome (modify configurtion of aster build to point to MED / HDF libs of Salome)...

PS2: There is also another BIG BUG in SALOME 3.2.1: there is a large performance issue and memory leak when displaying geometrical objects in a VTK view (already listed in known bugs, in fact, this feature in not coded completely now).
So in this case, just avoid choosing \"Display\" for a geometrical object in the MESH module. If you need to select faces / edges etc.. to create groups of elements/nodes, just prepare GROUPS of geometrical entities in GEOM module (very usefull feature) and select them in the tree from the MESH module.

I “admin” (sorry I don't know your name)
Unfortunately chmod didn't work.
I've issued the command:
chmod -v a+rw ASTK_SERV
inside the /opt/aster/ASTK folder.
I am not an expert in Linux, but I think this was the command you suggested.

Any more clues?

Thanks for your help.
