Another interesting feature -- if your case is not too big ! (ncells < 10000) -- would be to run valgrind on 1 time-step. You can tell the code where to find the valgrind executable (if present) in the same Advanced options button I wrote about in previous post. This will tell you whether you have some memory corruption in the code.

Hello
I run my calculations on a single processor, and i reserve 12GB of the memory as follows:  # PBS-l select = 1: ncpus = 1: mpiprocs = 1: mem = 12GB: Saturn = 1
Also the size of my mesh is (30,30,11), what bothered  is that the "CFILTER" works well for the  model Smagorinsky-dynamic !
Please find attached files: listing, erreur, error, sortie, and compil.log
Thank you very much for your help.

Hello,
Could you send me a "tar" of your setup (xml file from the graphical interface, all the Fortran sources, lance script) without the mesh of course ;-)
I assume I can launch a test-case on a simple channel flow with your model, can't I ?
I'll try to have look [disclaimer: when I have time :-(] and see if I can understand your problem.

And here are some comments, after a quick look at your listing file.
It seems you changed the default settings for LES simulations. The default are the following and are strongly advised, but perhaps did you change them on purpose ;)
- second-order in time for all variables - 10 sweeps on the RHS reconstruction for the pressure, 5 for the velocity
Also, be careful as it seems you are doing a restart simulation from a first simulation with different turbulent models. This isn't forbidden at all, but be aware that what you are doing could cause weird behavior.

Thank you for your advice and your jokes ;) ...

Nothing bad intended here ;-) sorry about my "jokes"... The fact is LES simulations can be quite sensitive :)
