Usage

import numpy as np
from bmi_dummy import BmiDummy

model = BmiDummy()
model.initialize("/dev/null")   # or a YAML config path, or ""

while model.get_current_time() < model.get_end_time():
    model.set_value("input", np.array([42.0]))
    model.update()
    dest = np.zeros(1)
    model.get_value("output", dest)   # always 0.0

model.finalize()

Optional YAML config

start_time: 0.0
end_time: 86400.0
time_step: 3600.0
input_vars: [rainfall, temperature]
output_vars: [streamflow]

All keys are optional — /dev/null (empty file) falls back to defaults.
