What it is
OpenFOAM is a free, open-source computational fluid dynamics toolbox for simulating fluid flow, heat transfer, and related physical processes. It provides pre-processing, mesh generation, solvers for different flow and physics problems, and post-processing tools. Built-in utilities include blockMesh and snappyHexMesh, and it can convert meshes from external formats. ParaView visualization is supported through the paraFoam launcher, reader modules, VTK conversion, and VTK output during simulations. OpenFOAM runs on Linux, macOS, and Windows, and supports self-hosted use. Its current release is v2606, released on 26 June 2026; GPU offloading is available as a compile-time option, with that work on a separate development track. It is distributed under the GNU General Public Licence. OpenCFD offers a one-year support package for installation, fixes, updates, CFD assistance, and code customization, subject to a yearly service-hours maximum. It does not respond to support queries without a prior package. Training courses are also offered, with prices provided through a schedule or enquiry process.

Plans and prices
Strong points and limits
Strong points
- Free and open source under GPL
- Includes mesh tools and multiple solver types
- Supports ParaView visualization workflows
- Available for Linux, macOS, and Windows
Limits
- Support queries require a prior support package
- Support hours are capped per year
- GPU work remains on a separate development track
- Training prices require schedule or enquiry
Who it suits
OpenFOAM suits science and engineering companies, consultancies, and universities working on fluid-flow or heat-transfer simulations. It is also relevant to users who can work with a GPL toolbox and self-hosted deployment.
Verdict
OpenFOAM provides a broad simulation workflow at no software charge, with support and code customization offered separately. Users should account for the support-package requirement and service-hour limit if they need assistance from OpenCFD.
