CreateBMG/BMGTOOLS

croco tools (pre/post-processing)

I have identified the IFREMER developed CreateBMG/BMGTOOLS packages that are mentioned in the CROCO manual. It seems from documentation online that they are freely distributed under license.

Does anyone know how to access the tool? I would greatly appreciate access to this tool (or anything newer in the same functionality space).

Hi,

You can download it here : https://mars3d.ifremer.fr/Les-outils/BathyMeshGridTOOLS/Acces-aux-codes

Note that the generated netcdf file will be in MARS3D model format, you will need a few modifications to transform it for the CROCO model.

That is great, thank you very much

On the following link
https://croco-ocean.gitlabpages.inria.fr/croco_doc/tutos/datarmor/tutorial_new_config.html#mesh-building-with-bmgtools

I’m wondering would you know how to get the scripts
convert_bathymars2croco.py
and
convert_fes2croco.py
Or indeed any of the scripts from
“/home/datawork-croco/datarmor-only/TRAININGS/TRAINING_2021/”

Thanks for reading

Hello,

The scripts are available on a forge at Ifremer. I made a doc that describe the scripts and where you can download an archive of the scripts.
Please follow this link : https://dyneco-dhysed.gitlab-pages.ifremer.fr/croco/croco_preproc_tools/
Let me know if you have any questions or if you need help.

Regards,

Matthieu

Hi again, it seems that I need a gitlab account with ifremer to access the tar file, could you email to joe.mcgovern@marine.ie?

Ok it’s done. You have access to the documentation ?

That’s great, thank you. I have the documentation for CreateBMG and CheckBMG in the download for them.

yes but for the python tools i made short documentation here : https://dyneco-dhysed.gitlab-pages.ifremer.fr/croco/croco_preproc_tools/

BMGtools is just a tool to make a grid with a graphical interface. The format in output match with another ocean model , so i made scripts to convert it in CROCO format. (convert_bathymars2croco.py)
If you want to INTERPOLATE bathymetry on the grid you should use the tool INTERP_BATHY before conversion
