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.; Modo foundry announced on November 7, 2024 that it is winding down development of Modo after the Modo 17.1 release, with no further feature or maintenance releases anticipated
  • They diverge on capability: ANSYS Fluent covers Turbulence model library, Modo covers Polygon 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.

Modo

  • Foundry announced on November 7, 2024 that it is winding down development of Modo after the Modo 17.1 release, with no further feature or maintenance releases anticipated
  • Support continues only until each customer's current contract term expires
  • Foundry does not guarantee that Modo will keep working on future operating system updates because no patches will be issued, and recommends customers migrate to alternative 3D workflows
  • Perpetual licences keep working but receive no further updates, bug fixes or support
  • The Modo forums closed in December 2024 and downloads, docs and the support knowledgebase were committed only until November 2025

Does ANSYS Fluent or Modo run on more platforms?
ANSYS Fluent runs on Windows, Linux. Modo 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 Modo is typically brought in for.

ANSYS Fluent covers Turbulence model library, Combustion and reacting flow, Multiphase flow, Meshing. Modo covers Polygon modeling, Subdivision surfaces, Sculpting, UV tools.

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.

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.

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.

ANSYS Fluent: Is there a free version?

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