I am running this model in offline mode, with input files for KPP, velocities, salt and temperature (see attached data.off). I am trying to see the diffusion due to the kpp scheme with the diagnostics package, and it seems that the output from the diagnostics package of KPPgTr01 is all zeros. Using the offline pkg KPPghatK is not written - I get an error in STDERR of:
