Equilibrium core is the engine driving DAVE. It is the core module that takes care of the geometric calculations, forces and finding equilibrium.

Unlike DAVE, the equilibrium core is not an open-source component. It is closed source and is (will be) available under a commercial license.

Equilibrium core can be used for free for educational purposes.

It is my intention to keep it as free as possible for as many people as possible. But since the offshore industry is not a large contributor to the open-source community, and I need to eat and kite as well, it will most probably not be free for use for commercial purposes.

At this moment the Equilibrium core is still in beta and can be downloaded and used for FREE. The current version will work until 2021.

The core consists of a single file: pyo3d.pyd which is a compiled python module.

It can be downloaded and installed automatically by DAVE or can be obtained and installed manually from here:

python 3.7 (windows x64) https://open-ocean.org/files/pyo3d.cp37-win_amd64.pyd
python 3.8 (windows x64) https://open-ocean.org/files/pyo3d.cp38-win_amd64.pyd
python 3.9 (windows x64) https://open-ocean.org/files/pyo3d.cp39-win_amd64.pyd

A linux version is available on request.
