NEMS configuration generation

Project description

NEMSpy

tests build version license style

NEMSpy generates configuration files (nems.configure, config.rc, model_configure, atm_namelist.rc) for coupled modeling applications run with a compiled NEMS binary (not included).

NEMS implements the National Unified Operational Prediction Capability (NUOPC), and configuration files built for NEMS will also work for most NUOPC applications.

Usage:

from datetime import datetime, timedelta

from nemspy import ModelingSystem
from nemspy.model import ADCIRCEntry, AtmosphericMeshEntry, WaveMeshEntry

# model run time
start_time = datetime(2020, 6, 1)
duration = timedelta(days=1)
end_time = start_time + duration

# returning interval of main run sequence
interval = timedelta(hours=1)

# directory to which configuration files should be written
output_directory = '~/nems_configuration/'

# model entries
ocean_model = ADCIRCEntry(
    processors=11,
    Verbosity='max',
    DumpFields=False
)
atmospheric_mesh = AtmosphericMeshEntry(
    filename='~/wind_atm_fin_ch_time_vec.nc',
    processors=1
)
wave_mesh = WaveMeshEntry(
    filename='~/ww3.Constant.20151214_sxy_ike_date.nc',
    processors=1
)

# instantiate model system with model entries
nems = ModelingSystem(
    start_time=start_time,
    end_time=end_time,
    interval=interval,
    ocn=ocean_model,
    atm=atmospheric_mesh,
    wav=wave_mesh,
)

# form connections between models
nems.connect('ATM', 'OCN')
nems.connect('WAV', 'OCN')

# define execution order
nems.sequence = [
    'ATM -> OCN',
    'WAV -> OCN',
    'ATM',
    'WAV',
    'OCN',
]

# write configuration files to the given directory
nems.write(
    directory=output_directory,
    overwrite=True,
    include_version=True
)

Output:
