Ariane with vtransform = 2?

edit

Hi everyone,

I'm trying to set up particle tracking with my CROCO output using Ariane, but whilst Ariane is nicely compatible with ROMS, I believe that the parameters it uses for the s-coordinates are using the old vertical coordinate system (vtransform = 1). Has anybody managed to figure out a way to make Ariane work with the new vertical coordinates?

Thanks!
