2wave

A hydrodynamic modulation model for short surface gravity waves riding on longer waves.

Features

• Solves the full wave crest and action balance equations in 1-d.
• Linear (1st order) or Stokes (3rd order) long waves
• Infinite long-wave trains or long-wave groups
• Effective gravity, propagation, and advection in curvilinear coordinates
• Optionally, output all tendencies at all time steps
• Output as Xarray Dataset

Getting started

Install 2wave

pip install git+https://github.com/wavesgroup/2wave

Run the model

from twowave import WaveModulationModel

m = WaveModulationModel()  # import the model
m.run()  # run the model
ds = m.to_xarray()  # convert the model output to an xarray dataset

Running the tests

git clone https://github.com/wavesgroup/2wave
cd 2wave
python3 -m venv venv
source venv/bin/activate
pip install -U .
pytest
