open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi Jose,
Thanks for your response. My aim is to convert my result file (Telemac2D) to NetCDF format to use it on the GNOME oil spill trajectory (NOAA) model. GNOME has the model input file format descriptions in NetCDF format for our Telemac results. So tried the code from the forum to convert to .nc format and it works fine I thought of modifying it for the GNOME instructed format.

I encountered the following error while trying the script.

Script called : slf2nc.py
Opening .slf file
Opening .r2s file

You have to take care of which method you are using and what python script version is it? Some time ago I saw a topic here about it, but it has been written on python2 environment.
Please, refer to Telemac_File.py script on python3 TELEMAC folder. this script presents almost all methods and functions you would need to create NetCDF file and manipulate your data.

Meanwhile, you can have a look at this topic to get the idea to write your netcdf:https://github.com/OpenDrift/opendrift/issues/213#issuecomment-805963006

Hi Sathish,

Did you figure it out to guide me? I am in need of this as well.

Thanks,
Hossein

Dear Hossein,

Sorry, I am not able to finish it.
