open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,

A problem appeared in one of my coupled T2D-Sisyphe simulation, the calcul stops at the first iteration because of Sisyphe.

This is what it writes at iteration 0

PART 0 : INITIALISING SISYPHE
forrtl: severe <257>: formatted I/0 to unit open for unformatted transfers, unit 7, file C:\TELEMAC\..\T2DRES
Image PC Routine Line Source
out245_win.exe unknown etc.

and it stops.

I tried:
- Telemac 2D without Sisyphe: it works,
- that simulation on another computer: it still doesnt work
- with a different but similar simulation: it works

Would someone have a guess? Thanks a lot!

Best regards
Jean

Hi

It looks like you filled Hydrodynamic file in the sisyphe steering file.
If you run in coupled mode, that's anormal

Hope this helps

Hello,

In coupled mode the logical units of files are changed, so it may happen that the telemac-2d results file has number 7. However there is somewhere something that writes on this file with a format (this is not normal but this was never reported so the reason probably lies in your specific case). It could be :

1) A hardcoded writing with explicit logical unit 7 given somewhere. If you do not have specific Fortran this is probably not the reason.
2) Some mismatch in the declaration of your files in the steering file.

To have more information on where the problem occurs, you could ask for some debug:

add: DEBUGGER = 1

in your steering files, and you will have a list of calls in both Telemac-2D and Sisyphe, that will tell us where this happens.

For your information, note that the logical unit of telemac-2d results file is in T2D_FILES(T2DRES)%LU, T2DRES being an integer which is the logical unit when there is no coupling, 8 if I remember well (it can be checked e.g. in the dictionary, in the string SUBMIT corresponding to the file).

Dear Christophe and Jean-Michel,

Thank you to both of you for your prompt answers.

Actually I have no fortran file, the mistake must be in my steering files.

I have done lately very close simulations (same mesh, different boundary conditions, almost same steering files) which worked. I attached the steering files 'cas' for TELEMAC and 'cas_peen_sis_coupled' for SISYPHE, I can't see the mistake!

Best regards,
Jean

the first one didn't make it

Hello,

The boundary conditions file is missing at least, and this must be the problem. We shall look how we can prevent this, as this file is mandatory.

With best regards,

Jean-Michel Hervouet
