Computational Fluid Dynamics

Gerris - is an Open Source Free Software library for the solution of the partial differential equations describing fluid flow. The source code is available free of charge under the Free Software GPL license. Gerris is supported by NIWA (National Institute of Water and Atmospheric research) and by the Marsden Fund of the Royal Society of New Zealand. The code is written entirely in C and uses both the GLib Library and the GTS Library for geometrical functions and object-oriented programming.

OpenFoam® - The OpenFOAM® (Open Field Operation and Manipulation) CFD Toolbox can simulate anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics, electromagnetics and the pricing of financial options. OpenFOAM is produced by OpenCFD Ltd and is freely available and open source, licensed under the GNU General Public Licence. Domain decomposition parallelism is fundamental to the design of OpenFOAM and integrated at a low level so that solvers can generally be developed without the need for any ’parallel-specific’ coding.
