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.; Plasticity limited plugin ecosystem compared to Rhino; fewer third-party extensions available
  • They diverge on capability: ANSYS Fluent covers Turbulence model library, Plasticity covers Smooth surface 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.

Plasticity

  • Limited plugin ecosystem compared to Rhino; fewer third-party extensions available
  • Young product with shorter track record; fewer industry case studies and community resources
  • No parametric history tree; may require different workflow for some users accustomed to feature-based modeling
  • Premium pricing for Indie users despite being positioned as affordable alternative

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

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.

Plasticity: What is Plasticity designed for?

Plasticity is a NURBS-based 3D modeler designed for concept and product design, prioritizing an artist-friendly workflow over parametric history-based modeling.

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.

Plasticity: What platforms does Plasticity support?

Plasticity runs on Windows, macOS (Intel and M-Series), Linux, and Ubuntu using Parasolid's geometric modeling kernel.

Source
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.

Plasticity: What is the pricing model for Plasticity?

Plasticity is a one-time purchase: Indie tier costs $149 and Studio tier is available at a higher price point. A 30-day free trial is available.

Source
ANSYS Fluent: Is there a free version?

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

Plasticity: Does Plasticity integrate with Blender?

Yes. Plasticity includes a Blender Bridge add-on that enables live-linking between Plasticity and Blender, allowing you to preview Plasticity models inside Blender with proper materials and lighting.

Source
Plasticity: What key features distinguish Plasticity from other CAD tools?

Plasticity features streamlined UI with context-sensitive widgets, chordal fillets, key bindings familiar to Blender users, radial menus, Dimension and Measure commands for absolute constraints, and handles complex Boolean operations on dense geometry.
