The OpenFOAM Foundation
OpenFOAM relies on third-party software packages for some important tasks: Scotch, PT-Scotch and Zoltan for domain decomposition and redistribution for parallel running. This is essential for non-trivial geometries for which simpler bisection-based methods produce inefficient decompositions. ParaView visualization application. This is essential for interactive pre- and post-processing, but may not be required on a remote […]
As the root user (e.g. typing sudo -i), programming tools can be installed by executing the following commands in a terminal: yum groupinstall ‘Development Tools’ yum install openmpi openmpi-devel yum install epel-release yum install –nogpgcheck qtwebkit qtwebkit-devel yum install –nogpgcheck CGAL CGAL-devel The Boost C++ library is installed automatically for GCAL under the name libboost_thread-mt.so, […]

Software that is included in the OpenFOAM source code base must conform to quality standards. Software quality can be split into two areas: Functional quality: how well it performs to a given design, based on requirements, i.e. its fitness for purpose. Structural quality: how well it meets requirements to be able to deliver functional quality, […]
OpenFOAM is a large piece of software (of the order of 1.5 million lines of code) in a complex area of scientific application. Since its open source release in 2004, it has become the CFD software of choice for many thousands of people from industry, government laboratories, academic institutions, etc., who download OpenFOAM and use […]
OpenFOAM is developed by a team of individuals who contribute their work to the project, with the support and consent of the companies that employ them. Contributions are made under the OpenFOAM Contributor Agreement (to facilitate enforcement of the free, open source licence), signed either by the individual, or by the organisation that employs them.

Function Objects OpenFOAM can carry out post-processing automatically while the simulation is running using function objects. In v2.3.0, a distinction is made between when a function object evaluates, and when it writes to file. The respective behaviour is controlled using the new evaluateControl and existing outputControl keyword settings. The specification for each entry is identical, […]
