Welcome to FOXES

Farm Optimization and eXtended yield Evaluation Software

FOXES is a modular wind farm and wake modelling code written in Python by Fraunhofer IWES. It has many applications, for example

• Wind farm optimization, e.g. layout optimization or wake steering,

• Wind farm post-construction analysis,

• Wake model studies, comparison and validation,

• Wind farm simulations invoking complex model chains.

The calculation is fully vectorized and its fast performance is owed to dask. Also the parallelization on local or remote clusters is enabled via dask. The wind farm optimization capabilities invoke the iwopy package which as well supports vectorization.
