The short version

  • Only Houdini has a free tier, so it costs nothing to try first.
  • Each has a real cost: COMSOL Multiphysics the base licence covers very little on its own and nearly every practical problem needs one or more add-on modules, each priced separately, so the quoted total is typically a multiple of the headline base figure.; Houdini houdini Indie at $299 per year requires annual gross revenue under $100K USD
  • They diverge on capability: COMSOL Multiphysics covers Coupled multiphysics solving, Houdini covers Procedural modeling.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

COMSOL Multiphysics

  • The base licence covers very little on its own and nearly every practical problem needs one or more add-on modules, each priced separately, so the quoted total is typically a multiple of the headline base figure.
  • Perpetual licences renew maintenance at 20% of the then-current price each year, and because that percentage applies to the whole module stack the annual bill grows as your module list does and as list prices rise.
  • No pricing at all is published, so procurement cannot benchmark or budget without a sales engagement, and comparisons against Ansys or SolidWorks Simulation are effectively impossible before that point.
  • Named Single-User and CPU-locked licences do not share, so a team of six that bought individual licences ends up with idle seats while a Floating Network Licence would have covered them, and switching licence type is a commercial renegotiation.
  • Solving strongly coupled systems is memory hungry and slow, and models that look modest in the GUI routinely need tens of gigabytes of RAM, so hardware cost is a real and often underestimated part of adoption.

Houdini

  • Houdini Indie at $299 per year requires annual gross revenue under $100K USD
  • Houdini Indie cannot be used in the same pipeline as commercial versions of Houdini
  • Houdini Indie and Apprentice save to their own .hipnc file format, which commercial Houdini pipelines do not share
  • The free Apprentice edition is non commercial, caps render resolution at 1920x1080 and watermarks output images
  • Houdini Indie ships with only 2 render tokens
  • Full DOP level simulation node access requires Houdini FX at $4,495 per workstation; Core at $1,995 exposes only SOP level pre built simulation assets
  • Extra render tokens cost $195

Answered from the vendors’ own pages

COMSOL Multiphysics: Does the base licence include CFD or structural mechanics?

Only limited capability. Serious CFD, structural, RF and acoustics work each require the relevant add-on module at extra cost.

Houdini: How much does SideFX Houdini cost?

SideFX Houdini pricing is not published on their website. Specific prices for commercial, educational, and non-commercial licenses must be obtained by adding items to your cart or contacting SideFX sales directly.

COMSOL Multiphysics: What does maintenance cost?

Perpetual licences include 12 months of updates and support, then renew at 20% of the then-current price per year.

Houdini: What license types does Houdini offer?

Houdini offers Commercial licenses (Houdini Indie for under $100K USD annual revenue, Houdini Core, Houdini FX, Houdini Engine), Non-Commercial licenses (Houdini Apprentice free, Houdini Education for Students and Schools), Rental options, and Annual Upgrade Plans. Volume-based discounts are available for Houdini Engine.

COMSOL Multiphysics: Which licence type should a team buy?

Floating Network if more than a couple of people use it, since it shares concurrency and includes cluster and cloud computing at no extra charge.

Houdini: Is Houdini available for free?

Yes. Houdini Apprentice is available free for non-commercial use. Houdini Education licenses are also available for students and schools at no cost.

Source
COMSOL Multiphysics: Is pricing published?

No. COMSOL publishes licence types but no prices; every purchase goes through a quote.

Houdini: Are volume discounts available for Houdini?

Yes. Volume-based discounts are available for Houdini Engine licenses. Rental and Annual Upgrade Plan pricing have been adjusted as of Houdini 21.
