OpenFOAM
OpenFOAM is the free, open source CFD software developed primarily by OpenCFD Ltd since 2004.
A free, open-source CFD toolbox for simulating fluid flow, heat transfer, multiphase flow, and related physics using finite-volume methods.
About the Project
Why use this?
OpenFOAM is a comprehensive open-source CFD software package built around finite-volume discretization and a flexible C++ object-oriented library. It includes solvers for incompressible and compressible flow, heat transfer, multiphase flow, combustion, particle tracking, and other coupled physics, along with meshing, pre-processing, and post-processing tools.
Aerospace engineers choose OpenFOAM for external aerodynamics, propulsion, combustion, multiphase systems, and custom solver development. Its open source nature allows users to inspect and modify the implementation, while its extensive solver library and parallel capability make it suitable for both research and industrial simulation.
