NEMS configuration generation

Project description

NEMSpy

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)

# 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('~/wind_atm_fin_ch_time_vec.nc')
wave_mesh = WaveMeshEntry('~/ww3.Constant.20151214_sxy_ike_date.nc')

# instantiate model system with model entries
nems = ModelingSystem(
    start_time, duration, 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(output_directory, overwrite=True, include_version=True)

Output:
