open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I'd like to try particles modules on my domain of interest with Telemac-2D.

My test configuration is based on the "riv_art : oil spill artificial river experiments" example.
The oil spill stearing file I use is the same than the one provided in this example.

The computation runs well and provides a serafin file (r2d_open.slf) and a ascii drogues file (oil_displacement.dat)

My issue is about the ascii drogues file :
The column related to X coordinates is supposed to give the longitude drogues positions...but it is full of stars ( ********* )
Whereas the column related to Y coordinates gives well the latitude drogues positions.

For this test, the initial drogues positions are filled in the user fortran file "oil_flot.f".
The initial position according to X coordinate is negative ( due to the longitude range of the domain )

Do you have an idea of the reason why my computation cannot write properly the X coordinates in the ascii file ?

Please find attached all the files required for running my test case.

Regards,

Audrey

Hello Audrey,

Which release of TELEMAC-2D are you using? If it is not the latest release (v8p2r1) or the trunk release, please use one of them first.

Otherwise, we cannot see any files. Please send a .zip file with all input files to run your computation (some extensions are not allowed). If the file is too heavy, please provide a link to download your input files.

Hello again,

Your 1st message was moderated by another moderator, but not the others, in particular the one with the zip files. I could have seen it since my first answer.

The issue is that your x coordinates need more than 7 characters before the decimal . due to the minus sign.

If you use the enclosed file, it should better work.

Hope this helps,

Hello again,

Looking at the listing, you should relax the solver accuracies: 1.E-18 is quite small and it is not reached during your computations. 1.E-8 may be enough depending on what you search. You can also increase the MAXIMUM NUMBER OF ITERATIONS FOR SOLVER.

Hope this helps,

Hello Chi-Tuan,

I put the file you provided in the 'user_fortran' repertory and it works perfectly

Thank you very much !

Thanks also for solver parameters.

And well noticed for updating ( I use the v8p2r0 version )

Kind regards,
Audrey
