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.; Creo every Creo user must buy a licence of the Creo Design Essentials package as a minimum before anything else can be added
  • They diverge on capability: ANSYS Fluent covers Turbulence model library, Creo covers Parametric modeling.
  • 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.

Creo

  • Every Creo user must buy a licence of the Creo Design Essentials package as a minimum before anything else can be added
  • Capabilities such as the Generative Design Extension, Creo Simulation Live, Advanced Assembly Extension and GD&T Advisor are sold as separate paid extensions
  • Published prices in the PTC Store cover only Creo Design Essentials, the Creo Suites and select extensions; the other design packages require talking to sales
  • Buying an individual extension requires contacting a sales representative rather than self service

Questions people ask

Is ANSYS Fluent or Creo better?
Neither clearly leads. ANSYS Fluent starts at On request and Creo at $29/month, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, ANSYS Fluent or Creo?
ANSYS Fluent starts at On request and Creo at $29/month.
Does ANSYS Fluent or Creo run on more platforms?
ANSYS Fluent runs on Windows, Linux. Creo runs on Windows.
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 Creo is typically brought in for.
What can ANSYS Fluent do that Creo cannot?
ANSYS Fluent covers Turbulence model library, Combustion and reacting flow, Multiphase flow, Meshing. Creo covers Parametric modeling, Direct modeling, Simulation, Generative design.

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.

Creo: Does Creo offer a free trial or evaluation version?

Yes, PTC offers a free trial of Creo. Users can instantly access a fully functional trial of Creo. The page also provides a 30-day free trial option for both Creo and Creo+.

Source
ANSYS 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.

Creo: What licensing options does Creo provide?

Creo supports flexible licensing options including on-premises solution and Creo+, a SaaS offering. Licensing tiers support solo designers, small teams up to 5 licenses, and growing teams with 5 or more licenses. PTC also offers a startup program with free or discounted access.

ANSYS 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.

Creo: Is Creo free for students and educators?

Yes, Creo is available for free to students and educators through PTC Education. Students and educators from grade school through university can get free access to Creo to learn advanced CAD capabilities.

ANSYS Fluent: Is there a free version?

There is a student edition with cell count limits, suitable for learning but not for production work.
