Capytaine: a linear potential flow BEM solver with Python.


Capytaine is Python package for the simulation of the interaction between water waves and floating bodies in frequency domain. It is built around a full rewrite of the open source Boundary Element Method (BEM) solver Nemoh for the linear potential flow wave theory.


On Windows, macOS and Linux, using the Conda package manager:

conda install -c conda-forge capytaine
