Hello

I'm working on a case I was given. With no use of Graphical Interface.

I can run the case without problem. So I did few iterations, stopped and wanted to restart. But it doesn't work.

ileaux and iecaux are activated (=1) even if I don't know if they're still generated in Saturne 2.1 and in the cs_user_scripts.py, I've puth the path at the beginning :

domain.restart_input='RESU/20210101-1210/checkpoint'

but it doesn't work

did I miss someting???


thanks for your help

Hello,

The syntax seems correct, but you might have a typo in your path: I would expect the path to start with 2012 (this year) and not 2021 as above...

hello Yvan
 
no, the mistake is just in the post, when writing the path...but I ran with RESU/20120201-1210/checkpoint .... and I have the following message :
SIGSEGV signal (forbidden memory area access) intercepted

Hello,
Could you post the stack trace (details around the SIGSEGV message) from the error or listing file ?

Hello,
Between the first run and the restart try, I don't change anything in the subroutines etc....
In the checkpoint file, I just have 3 files: auxiliary, main and radiative_transfer ... no ileaux etc...
thanks again

Hello Christine,
If it's possible, could you post the study please ?

Hi Yvan,
Even if the work is for your company I'm not sure I can send the study case and in particular on the forum. I should ask before.
I'm adding subroutines to the case I was given. Maybe I'm doing it in the wrong way. Saturne is really new to me so I'm trying..
In fact, I add some pieces of programs in different existing subroutines (uscpcl, usproj). I've no problem of compilation and  run, it's just when I try to do a RESTART. Could it come from this?
Is it normal if I don't have any other files in the checkpoint directory?
Best regards
Christine
 

Hello Christine,
If the data is confidential, but available to EDF, you may e-mail it to saturne-support@edf.fr.
Unless the mesh is small (< 4 Mb), it is preferable to send a link to a large data transfert service (hidden ftp directory) rather than as an attachment, as we do have e-mail caps.
Best regards,
  Yvan

ciao Yvan,
 
I'm waiting for the reply to know if I can or not, send these files.
Meanwhile, can you tell me how I can have the output files in a txt format? I've looked everywhere in usini1.f90 and usproj.f90 but nothing...I know we can obtain them when using the Interface but without, I can't find. (I mean the files that are obtained in the postprocessing directory, not the probes)
Thank you very much
Christine

Hello Christine,
With version 2.0, set optchr = 'text' in usini1.f90 (search for either optchr or text and you will have both an explanation and an example).
With version 2.1 or above, set format_options[] = "text" in the cs_user_postprocess_writers function of cs_user_postprocess.c (same here, search for those words and adapt the function).
Best regards,
  Yvan
