1. Learn how to use COERbuoy

1.1 Basic usage

For a quick guide into using COERbuoy, please see section 3: Run COERbuoy. If you use jupyther, there is a notebook available with a few examples. The most comprehensive overview over COERbuoy is given in the manual.

1.2 Writing a controller

Please see the examples using python or MATLAB in the example section.

1.3 Writing a WEC

The inclusion of custom WECs is possible, but not offically suported. However, an example is available.

2. Installation

Download python3.

Install COERbuoy using pip:

Variant 1
py -m pip install COERbuoy

Variant 1
python3 -m pip install COERbuoy

3. Run COERbuoy

NOTE: The commands how to run python might differ between systems, and the ones presented here might not work on every machine. Please refer to https://www.python.org/ to find the correct commands for your system.

Run graphical user interface:

Variant 1		Variant 1
py -m COERbuoy.GUI		python3 -m COERbuoy.GUI

3.1. Command line:

Brettschneider wave with significant wave height 1.5 m and wave energy period of 6 s and a linear generator damping:

Variant 1
py -m COERbuoy --bretschneider_wave 1.5 6 results.csv linear

Variant 1
python3 -m COERbuoy --bretschneider_wave 1.5 6 results.csv linear

Regular wave with height 1.5 m and period of 6 s and a linear generator damping:
