OpenFOAM
OpenFOAM an open source toolkit for continuum mechanics ideally suited for computational fluid dynamics (CFD) both as a teaching and a research tool. The packaging of OpenFOAM is done by Open Ltd. at the ESI Group and distributed under the GNU Public License (GPL) by the OpenFOAM foundation. The fundamental classes provided by OpenFOAM allows the rapid construction of numerical solvers for continuum mechanics solver. A nascent program for providing teaching material and tutorials for OpenFOAM has been started at IIT Bombay under the FOSSEE project to make engineering students and teachers to make use of open source technologies.
