open TELEMAC-MASCARET The mathematically superior suite of solvers

I am wondering if the language plays any role in this. It seems that you run the computation in French, but in the systel you have "language: 2". Just a thought...

Costas

PS. Try using console redirection to capture the output of the computation in a file instead of the screen, e.g.It will make posting the errors easier.

You're right.

Looks like the language change everything.
I tried a validation case with keywords in english and the computation is faster.

Validation cases are sometimes in french or in english... how can I manage to work with both language?

If I switch PROCESSEURS PARALLELES to PARALLEL PROCESSORS in the malpasset case... I get an error

Apart from setting the language globally in the systel.cfg, there is a 'LANGUAGE' option in telemac2D cas file (1 for French, 2 for English) that might help adding it in your case.

However, I remember running the malpasset case (which is in french) without any modifications regarding language, and my systel language setting was always 2... Of course, all the keywords in the cas file should be language-consistent, i.e. you shouldn't mix french with english keywords.

Yes it looks like there is a bug with language :

With this steering file...


I get this T2CAS






and this message, as you can see gretel can't work because there is no partition to merge




in my directory... geometry, boundary condition, reference file are split in two partition but I only have one RES

There is something really strange going on. It is like the computation is running in 'hybrid' scalar-parallel mode! I would suggest to reinstall telemac.

Use the automatic installer once more and if that doesn't solve the problem, then try to download the sources manually and compile them yourself.

Just another thought. Try moving your project directory to a shorter path, e.g. d:\t2d-malpasset. Long paths have caused problems in the past...

Thank you Costas and Christophe.

Your advice helps me. I don't think the path was the cause but it helps me.

I used a benchmark folder and for an unknown reason, there was a remaining file from another run (done with my old computer).

This file (that hasn't been deleted because the computation had not been completed) was the reason why I met a keyword conflict.

I really appreciate your help.

Thanks to you, the problem is solved.
Just in case, if users have keywords repeated twice in the listing (and not in the steering file), make sure that your directory is clean.

It is possible that you ran the scalar mode first, therefore creating a local executable without the MPI directive, and then trying in parallel. Because the local executable is there already and has not changed, TELEMAC does not see that you have switch configuration to parallel.

Try deleting your local executable and try the parallel only again.

Hope this helps,
Sébastien.
