Framework for studying fluid dynamics.
|alt:||Travis CI status|
FluidDyn project is an ecosystem of packages for research and teaching in fluid dynamics. The Python package fluiddyn contains:
- basic utilities to manage: File I/O for some esoteric formats, publication quality figures, job submission on clusters, MPI
- powerful classes to handle: parameters, arrays, series of files
- simplified interfaces to calculate: FFT, spherical harmonics
and much more. It is used as a library in the other specialized packages of the FluidDyn project (in particular in fluidfft, fluidsim, fluidlab and fluidimage).
The simplest way to install fluiddyn is by using pip:
pip install fluiddyn [--user]
Add --user flag if you are installing without setting up a virtual environment.
You can also get the source code from Bitbucket or from the Python Package Index. It is recommended to install numpy before installing fluiddyn. The development mode is often useful if you intend to modify fluiddyn. From the root directory:
python setup.py develop
|Minimum||Python (>=3.6), numpy matplotlib h5py psutil|
|Full functionality||h5py h5netcdf pillow imageio mpi4py scipy pyfftw (requires FFTW library), SHTns|
|Optional||OpenCV with Python bindings, scikit-image|
Note: Detailed instructions to install the above dependencies using Anaconda / Miniconda or in a specific operating system such as Ubuntu, macOS etc. can be found here.
From the root directory:
Or, from the root directory or any of the “test” directories:
python -m unittest discover

The FluidDyn project started in 2015 as the evolution of two packages previously developed by Pierre Augier (CNRS researcher at LEGI, Grenoble): solveq2d (a numerical code to solve fluid equations in a periodic two-dimensional space with a pseudo-spectral method, developed at KTH, Stockholm) and fluidlab (a toolkit to do experiments, developed in the G. K. Batchelor Fluid Dynamics Laboratory at DAMTP, University of Cambridge).
Keywords and ambitions: fluid dynamics research with Python (>= 3.6), modular, object-oriented, collaborative, tested and documented, free and open-source software.
FluidDyn is distributed under the CeCILL-B License, a BSD compatible french license.
