The short version

  • Only Twinmotion has a free tier, so it costs nothing to try first.
  • 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.; Twinmotion epic Games' own pricing announcement (unrealengine.com/twinmotion.com) sets an individual Twinmotion seat at $445 per year, and the bundled Unreal Subscription covering Twinmotion, Unreal Engine and RealityCapture together at $1,850 per seat per year, once a company's annual gross revenue exceeds $1,000,000 USD; below that threshold the same software is free, including for commercial use, which makes list price highly dependent on company size rather than usage.
  • They diverge on capability: ANSYS Fluent covers Turbulence model library, Twinmotion covers Real-time rendering.
  • 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.

Twinmotion

  • Epic Games' own pricing announcement (unrealengine.com/twinmotion.com) sets an individual Twinmotion seat at $445 per year, and the bundled Unreal Subscription covering Twinmotion, Unreal Engine and RealityCapture together at $1,850 per seat per year, once a company's annual gross revenue exceeds $1,000,000 USD; below that threshold the same software is free, including for commercial use, which makes list price highly dependent on company size rather than usage.

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.
