fabm0d not reading fabm.yaml. Do I need an nml file for fabm0d?

[thejusmahajan]

Good morning all,
I am probably missing out with an obvious oversight. Here is my issue.

I adapted gotm/npzd model and ran successfully with gotm 1d model with forcing from <GOTM_DIR>/cases/gotland with yaml files fabm.yaml and gotm.yaml.
Now that I want to run fabm0d with the same fabm.yaml, it outputs an error

0D FABM driver (using GOTM infrastructure)
FABM version: unknown (unknown branch)
Started on 20250218 092958.395

init_run

---

    reading model setup namelists from run.nml

FATAL ERROR: init_run
I could not open run.nml for reading.
clean_up
STOP 1

My install of fabm0d is by this cmake command,
cmake <FABM_DIR>src/drivers/0d/ -DGOTM_BASE=<GOTM6_DIR>/code/.

I am guessing that I miss nml file. Am I missing something obvious? Kindly help.

Hi there. The 0D driver (fabm0d) uses its own set of files to configure the simulation and environment. For instance, the run.nml mentioned. None of these files are shared with GOTM - ony the biogeochemical model configuration (fabm.yaml) is. An example of the files needed for the 0D driver is inlcuded in the repository at testcases/0d.
