The Numerical Tour of Fluid Dynamics, developed by Olivia Miraucourt and Simon Garnotel, aims to provide CFD community with validated algorithms for simulation of flows. We share also meshes to test these algorithms in differents geometries.

We are members of the VIVABRAIN project funded by the French Agence Nationale de la Recherche. Our work consists of simulating blood flows in cerebral vascular network but our codes are applicable for any type of fluids in any kind of geometries.

If you're novice in CFD, don't worry ! You just have to download the library for the finite element method FreeFem++. This library is free and very easy to install. Once the library is installed, you can directly test our codes to solve the fundamental equations of fluid dynamics : Stokes and Navier-Stokes.

If you want to contribute to this Numerical Tour, you're welcome ! Contact us and send us your meshes and codes. We will be glad to expand the team.

Some thinking about fluidity

"The cognitive life of things is about things in motion; it is about hybridity, fluidity and genuinely interactive relationships between brains, bodies and things." Malafouris & Renfrew

"When you accurately perceive the fluidity of things, you can also begin to perceive the constancy behind them the creative, transformative, boundless, immutable Tao." Lao Tzu

"The goal in life is to be solid, whereas the way that life works is totally fluid, so you can never actually achieve that goal." Damien Hirst

"Things are fluid in this world, and if you don't remain fluid, you get lost in the sauce." Talib Kweli
