Computational fluid dynamics solver for turbulence, combustion and multiphase flow

The short version
- Each has a real cost: 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.; V-Ray licences are subscription only with no perpetual option listed for any product
- They diverge on capability: ANSYS Fluent covers Turbulence model library, V-Ray covers Ray tracing.
- Prices and features above were last checked on 31 August 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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.
V-Ray
- Licences are subscription only with no perpetual option listed for any product
- Subscription terms renew automatically
- Cloud rendering runs on separately purchased credits, with the Pro tier at $25.30 a month for 1,000
- Enterprise pricing requires contacting sales

Questions people ask
- Is ANSYS Fluent or V-Ray better?
- Neither clearly leads. ANSYS Fluent starts at On request and V-Ray at $29/month, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, ANSYS Fluent or V-Ray?
- ANSYS Fluent starts at On request and V-Ray at $29/month.
- Does ANSYS Fluent or V-Ray run on more platforms?
- ANSYS Fluent runs on Windows, Linux. V-Ray runs on Windows, MacOS, Linux.
- What is ANSYS Fluent best used for?
- ANSYS Fluent is most often used 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. Of those, certifying an aerospace component where the customer specification names a validated commercial cfd solver and predicting thermal performance of a data centre or electronics enclosure before committing to a mechanical design are not what V-Ray is typically brought in for.
- What can ANSYS Fluent do that V-Ray cannot?
- ANSYS Fluent covers Turbulence model library, Combustion and reacting flow, Multiphase flow, Meshing. V-Ray covers Ray tracing, Global illumination, GPU rendering, CPU rendering.
Answered from the vendors’ own pages
ANSYS Fluent: 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.
V-Ray: What is included in Chaos software subscriptions?
All Chaos subscriptions include free support, access to a large community of professionals, continuous updates, and a 14-day money-back guarantee. Annual subscriptions save 45% versus monthly billing. Use of AI credits voids the refund right.
SourceANSYS Fluent: 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.
V-Ray: Does Chaos offer enterprise pricing?
Yes, Chaos provides enterprise pricing plans for teams with more than 10 licenses. Enterprise customers should contact the Chaos sales team directly for custom pricing quotes tailored to their specific needs.
SourceANSYS Fluent: 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.
ANSYS Fluent: Is there a free version?
There is a student edition with cell count limits, suitable for learning but not for production work.
