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.
Overture Overture is an object-oriented code framework for solving partial differential equations in serial and parallel computing environments. It provides a portable, flexible software development environment for applications that involve the simulation of physical processes in complex moving geometry. It is implemented as a collection of C++ libraries that enable the use of finite difference and finite volume methods at a level that hides the details of the associated data structures, as well as the details of the parallel implementation.
