Reading Delf3D Flow NetCDF output into parcels

[VeckoTheGecko]

I've been working with Delft3D Flow simulations which have an option to export to NetCDF files. The format of the output NetCDF of Delf3D Flow simulations and the input of parcels flowfields are different.

Are there existing functions (within the codebase, or external tools) to wrangle flow data from Delf3D Flow simulations into the parcels format?

If not, I may develop these functions. Would this be a suitable fit to have somewhere in the parcels codebase?

Thanks @VeckoTheGecko! No, we don't have out-of-the-box support for Delft3D NetCDF files yet. You could try to write a function like FieldSet.from_nemo()? See https://github.com/OceanParcels/parcels/blob/master/parcels/fieldset.py#L425-L499

I know that Abdel Nnafie has worked with Parcels and Delft3d; but not sure if his code is online. You could try to contact him?

Sounds good. I've just created an issue for it, happy to work on it over the next couple weeks (unless my work takes me in a different direction).

Might reach out to Abdel, but from an initial look it doesn't look too bad :).

Also, are there guidelines for contributing to parcels? (eg. instructions on how to install it in an interactive way; not sure if it would be different with parcels as it uses Anaconda)

[VeckoTheGecko]

All good. Found the developer install instructions in the installation section of the website.
