[ecco-support] [EXTERNAL] How to design new traits in darwin

[Wang, Ou (US 329B)]

Hello Francesco,

If the model stops while reading a namelist file, such as data.darwin in your case, it will print out an error message indicating the specific line and column of the namelist file where the error was encountered. This aids in debugging, for instance, if there is a typo in the namelist file, and/or if the code does not include a new parameter that is provided in the namelist file.

Best,
Ou Wang

Subject: [EXTERNAL] [ecco-support] How to design new traits in darwin
Hi everyone,

I am new to this mailing list, then please excuse me if this kind of message is off-topic here.

I'm working with Darwin, in particular I'm trying to define a new trait to use in the darwin_plankon.F routine.

To do this, I added the new trait definition in
- DARWIN_TRAITS.h
- darwin_check.F
- darwin_read_traits.F

Being non allometric as Xmin, I also defined the corresponding parameter (as a_Xmin) in:
- DARWIN_TRAIPARAMS.h
- darwin_read_traitparams.F

In order to call in darwin_generate_allometric.F something like this:
Xmin(jp)       = a_Xmin(g)

However, in running time the model stops while reading the data.darwin namelist.
I think I'm missing something, maybe I am not considering some subroutine or I have misunderstood how to design a new trait.
Do you have any suggestions or some advices?

Thank you very much for the help.

Best regards,

Francesco Dattilo
