runcase

[Christine Leroy]

Hello everyone,
 
I'm trying to run a case on saturne 2.0.3 (with ncs 204)
 
As the case I received is without .xml, I'm trying to adapt the runcase to my platform.
 
at lines 228 and 239, which path should I put?
 
my installation is as follow:
 
I've a /home/leroy/SATURNE_src directory, containing the downloaded sources file, where I've created the build directories and the code is installed in /home/leroy/software/saturne/cs-203
 
when I put in lines 228 and 239  the following path :
/home/leroy/software/saturne/cs-204, I have the following error at line 488 :
 
line 488: /home/leroy/software/saturne/cs-203/bin/cs : no such file or directory
 
so I tried to find a cs dorectory, also in the source or build directories, but I couldn't find.
 
looking at line 488 in the runcase, it seems that there should bin a cs directory containing the check_consistency file. I found in : /home/leroy/SATURNE_src/ncs-2.0.4/bin, a file named cs_check_consistency.py and I tried to put at line 228 and 239 the following path : /home/leroy/SATURNE_src/ncs-204 but the problem remains :
line 488: /home/leroy/SATURNE_src/ncs-2.0.4/bin/cs : no such file or directory
 
Can someone help me fix this problem? Thank you very much

Hello Christine,
You must create a new case to generate the runcase. Next, copy & paste your sources/xml/datas in the SRC/DATA folders.

Ciao JF,
 
Thank you,  I didn't know that Saturne would fill in the runcase itself. Better like this.
I now have the following problem: I couldn't run the case because, cgns was not installed...so I did a new installation and it's ok for cgns. But now I have the following message in the compil.log, and I don't know what it means (before installing cgns I didn't have any problem during the compilation phase) :

Traceback (most recent call last):

What is it about?
thank you in advance

Hello,

A bug regarding modules was fixed in version 2.0.4, and might explain your problem (you seem to be using version 2.0.3, while the latest is 2.0.4).

A second bug was fixed later, so if you still have issues with this, replace the file "bin/cs_exec_environment.py" from the Code_Saturne Kernel (ncs-2.0.4) with the one attached.

Best regards,

  Yvan

Ciao Yvan,

In fact I installed the version 2.0.3 at first, then I had a problem and following advices from the forum, I installed the ncs-2.0.4. I let the rest from version 2.0.3 and that's also why my cs directory is cs-203. 

So the problem remains, do you think I should install all from version 2.0.4 to fix that problem?

Maybe I'm also mistaking when trying to run the case : I do ./runcase from the scripts directory since I don't have any .xml, all is in subroutines.
 
Thanks again
 
Christine

Hello Christine,

If you have version 2.0.4, simply using the cs_exec_environment.py atached to my previous post instead of the one in ncs-204/bin and re-running "make install" should be enough (no need to re-run configure if you still have the build directory).

Best regards,

  Yvan

Ciao Yvan,
 
I already changed the file as you told me but first I didn't do the "make install " etc...so I did...but still same error. 

I also tried, re-running configure again even if...and nothing changed. The problem still remains.

Hello everyone,

Sorry if insisting, but I really can't find a way to run the case, I still have the same error message:
 
Traceback (most recent call last):
  File "/home/leroy/software/saturne/cs-203/bin/code_saturne", line 127, in <module>
    main(sys.argv[1:])

    commands[command](argv[1:])
  File "/home/leroy/software/saturne/cs-203/bin/code_saturne", line 75, in compile
    cs_compile.main(argv)
  File "/home/leroy/software/saturne/cs-203/lib/python2.6/site-packages/ncs/cs_compile.py", line 288, in main
    set_modules() # Set environment modules if present
  File "/home/leroy/software/saturne/cs-203/lib/python2.6/site-packages/ncs/cs_exec_environment.py", line 169, in set_modules

    errread, errwrite)
  File "/usr/lib64/python2.6/subprocess.py", line 1092, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory
 
Any idea of what kind of error it can be?

Thank you for your help

Hello Christine,

The bug was reproduced and fixed yesterday, and a version 2.0.5 with corrections will be released next week.

While waiting, you may try to replace the Makefile.in file in the ncs-204 directory by the one attached, and reinstall the code.

This should fix the bug for you.

Best regards,

  Yvan

Ciao Yvan,
 
Thank you.

I've re-compiled everything with the new Makefile.in and now when I run the case, it's ok for the compilation.

But I now have a problem with cgns. As the mesh I was given is in cgns format, I installed cgns and compiled again the saturne code. So I put the cgns option and it seemed to be ok since I had the " CGNS (CFD General Notation System) support: yes"  when installing ecs. But probably, Saturne can't find the path for the cgns libraries since I have the following message when trying to run my case :
/home/leroy/software/saturne/cs-204/bin/cs_preprocess: error while loading shared libraries: libcgns.so.3.1: cannot open shared object file: No such file or directory

Where should I tell Saturne how to find these libraries? in my computer they're at this address : /usr/local/lib/libcgns.so.3.1

I have the same error message if I try to run the version 2.1 of Saturne.

Thanks in advance.

Christine
