ANSYS Fluent
Computational fluid dynamics solver for turbulence, combustion and multiphase flow
As of 31 August 2026, ANSYS Fluent's pricing is not published; the vendor quotes on request. The CFD solver most aerospace, automotive and turbomachinery engineering teams validate against, with physics models that have decades of published correlation behind them. Softwr lists it under CAD. ANSYS Fluent is made by Ansys, part of Synopsys, available on Windows, Linux.
Overview
What ANSYS Fluent does
Fluent is a finite volume computational fluid dynamics solver. It meshes a geometry, applies turbulence, combustion, radiation, multiphase or reacting flow models, and solves the governing equations, typically across dozens or hundreds of compute cores. It is used to predict drag on a vehicle, cooling in an electronics enclosure, mixing in a chemical reactor or flame stability in a gas turbine, in cases where building the physical prototype costs more than the licence. The distinguishing thing is validation history. Fluent's turbulence and combustion models have been benchmarked in peer-reviewed literature for thirty years, and regulators, certification bodies and internal engineering standards in aerospace and nuclear frequently name it explicitly. That is a commercial moat that has nothing to do with the user interface: an open source solver may be numerically equivalent and still fail because your customer's specification says the analysis must be reproducible in a named tool. Buyers are simulation groups inside large manufacturers and the engineering consultancies that serve them. The trade-off is cost structure. A Fluent seat licence is only the entry fee; running a large case in parallel requires high performance computing packs licensed by core count, and a serious solve capability runs into six figures a year before hardware. Synopsys completed its $35bn acquisition of Ansys in July 2025 and began combining the portfolios in 2026, so bundling, packaging and the sales relationship are all in flux.
What people use it for
- Certifying an aerospace component where the customer specification names a validated commercial CFD solver
- Predicting thermal performance of a data centre or electronics enclosure before committing to a mechanical design
- Combustion analysis for a gas turbine or industrial burner where detailed chemistry models are required
- A consultancy that must hand a client an auditable analysis in a tool the client's own engineers can reopen

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about ANSYS Fluent.
- Solver seats and HPC packs are licensed separately, and the packs scale by core count, so the cost of running a large case in parallel can exceed the base licence several times over and is the line item that surprises first-time buyers.
- Ansys does not publish any pricing, and quotes vary widely by region, industry and negotiating position, so a smaller firm has no way to know whether it is being charged fairly relative to a large account.
- Synopsys completed its acquisition of Ansys in July 2025 and started shipping combined capabilities in 2026; packaging, bundling and account teams are changing, and buyers on multi-year agreements should expect renewal terms to be renegotiated on a different basis.
- Getting trustworthy results demands genuine CFD expertise in meshing, turbulence model selection and convergence assessment, so the licence is useless without a specialist, and the specialist is harder to hire than the software is to buy.
- Licences are typically served from a network licence manager, which means concurrent-use contention inside a busy simulation group; engineers queue for solver tokens, and organisations end up buying spare seats purely to avoid the queue.

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
How much does Fluent cost?
Ansys does not publish pricing. Expect an annual lease per solver seat plus separately licensed HPC packs for parallel cores, with the total for a serious capability running into six figures a year.
Is Fluent still an Ansys product?
Yes, but Ansys is now part of Synopsys following the acquisition that completed in July 2025, and the two portfolios are being combined.
Can OpenFOAM do the same job?
Numerically it can cover a lot of the same physics at no licence cost, but it lacks the meshing workflow, support and the validation pedigree that certification and customer specifications often require.
Is there a free version?
There is a student edition with cell count limits, suitable for learning but not for production work.
