The short version

  • Only Mari 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.; Mari the full annual licence is $1,289 paid annually, and a short term quarterly rental is $949 per quarter
  • They diverge on capability: ANSYS Fluent covers Turbulence model library, Mari covers High-resolution painting.
  • 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.

Mari

  • The full annual licence is $1,289 paid annually, and a short term quarterly rental is $949 per quarter
  • The cheap $299 per year or $35 per month subscription is restricted to a single licence for people working alone or in small companies
  • Node-locked and floating are separate licence types you must choose between
  • All listed prices are before applicable taxes
  • A separate non-commercial licence exists, so commercial use requires a paid tier

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.

Mari: What is Mari's pricing?

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.

Mari: Does Mari offer a free trial?

Mari offers a free 30-day trial with unrestricted access to help users evaluate the software before purchasing.

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.

Mari: Does Mari offer student pricing?

Yes, Mari offers free or discounted access to all Foundry products for students, as well as free non-commercial licenses for learning and exploration.

ANSYS Fluent: Is there a free version?

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