FluidDyn documentation

FluidDyn logo

The FluidDyn project aims at promoting the use of open-source Python software in research in fluid dynamics. The project provides some Python packages specialized for different tasks, in particular

  • transonic, to make your Python code fly at transonic speeds!

  • fluidfft for 2D and 3D Fast Fourier Transforms,

  • fluidsim for numerical simulations,

  • fluidlab for laboratory experiments,

  • fluidimage for processing of images of fluid,

  • fluidsht for Spherical Harmonic Transforms.

This documentation presents the FluidDyn project and the package of the same name, which is the base package on which the other packages depend on. For the specific documentations of these specialized packages, follow the links above.
