cfMesh is an open-source library for volume mesh generation based on OpenFOAM. It implements various meshing workflows for volume mesh generation needed for CFD simulations with OpenFOAM. It is already a part of foam-extend, OpenFOAM for Windows, Caelus and OpenFOAM+ released by ESI. This repository is intended for contribution and collaborative development. If you have a new meshing algorithm or interested in contributing to cfMesh, do not hesitate to contact us. Please note that this code is not the same as CF-MESH+, which is a commercial product offered by Creative Fields Holding.

The goal of this project is to open the OpenFOAM CFD toolbox to community contributed extensions. Visit https://sourceforge.net/p/openfoam-extend/wiki/Home/ for more information. OPENFOAM(R) is a registered trademark of OpenCFD Limited.

The foam-extend project is a fork of the OpenFOAM® open source library for Computational Fluid Dynamics (CFD). The goal of this project is to integrate community contributions to the foam-extend CFD simulation toolbox. It is an open project welcoming and integrating contributions from all users and developers.

The project is an update of the work by the OpenFOAM Turbomachinery Working Group, that was initiated at the Second OpenFOAM Workshop in Zagreb, June 2007. Objectives: * Develop OpenFOAM and FOAM-extend extensions for turbomachinery applications, including pre-processing, solution methods, and post-processing. * Provide tutorials on how to produce accurate results using OpenFOAM and FOAM-extend in turbomachines. * Distribute relevant validation test cases and corresponding OpenFOAM and FOAM-extend applications. * Provide a test-harness for new releases of OpenFOAM and FOAM-extend. * Provide Best Practice Guidelines for CFD in turbomachines.

ISAAC (Integrated Solution Algorithm for Arbitrary Configurations) is a computational fluid dynamics (CFD) code developed to test and apply high order turbulence models for compressible flows around complex geometric configurations.

Gerris is a tool for generic numerical simulations of flows (CFD), in geometrically complex geometries and including adaptive, multiphase and interfacial flows capabilities.

FFTW++ is a C++ header class for the FFTW Fast Fourier Transform library that automates memory allocation, alignment, planning, wisdom, and communication on both serial and parallel (OpenMP/MPI) architectures. In 2D and 3D, hybrid dealiasing of convolutions substantially reduces memory usage and computation time. Wrappers for C, Python, and Fortran are included.

UPDATE: As of March 2023, the CFDTOOLS project has moved its public repository to NASA's official organization on GitHub: https://www.github.com/nasa/cfdtools While this repository will remain available, it will no longer receive updates or be monitored for issues. Please see the link above for latest releases and issue status. ---- The CFD Utility Software Library (previously known as the Aerodynamics Division Software Library at NASA Ames Research Center) contains nearly 30 libraries of generalized subroutines and close to 100 applications built upon those libraries. These utilities have accumulated during four decades or so of software development in the aerospace field. David Saunders and Robert Kennelly are the primary authors, but miscellaneous contributions by others are gratefully acknowledged.

This solver represents an addition to the open-source CFD package OpenFOAM. The solver is used to simulate the deflagration-to-detonation transition in hydrogen-air mixtures. Prominent features are described below. Additional description is available in the pdf file included. For a more detailed description download Florian Ettner's thesis (in German) from http://www.td.mw.tum.de/tum-td/de/forschung/dissertationen/download/I2013/Ettne13.pdf [8.6 MB] A shorter description (in English) can be found in the following publiction: http://www.hindawi.com/journals/jc/2014/686347/

Construct2D is a grid generator designed to create 2D grids for CFD computations on airfoils. The grids are generated in Plot3D format. The only required input file is the set of coordinates defining the airfoil geometry, using the same format as XFoil, the popular vortex-panel code for airfoil analysis. Construct2D can create grids with O topology (recommended for airfoils with a blunt trailing edge) or C topology (recommended for airfoils with a sharp trailing edge). Now available in version 2.0: hyperbolic grid generation to create higher quality grids in a fraction of the time compared to elliptic grid generation. Elliptic grid generation is still available also. Smooth airfoil surface spacing is handled automatically with user-controlled clustering parameters. Also included is a visualizer written in Python with matplotlib.
