The short version

  • Only FreeCAD 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.; FreeCAD no pricing published; product is completely free and open-source
  • They diverge on capability: COMSOL Multiphysics covers Coupled multiphysics solving, FreeCAD covers Parametric 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.

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.

FreeCAD

  • No pricing published; product is completely free and open-source
  • Donations are optional and voluntary for project support

Questions people ask

Is COMSOL Multiphysics or FreeCAD better?
Neither clearly leads. COMSOL Multiphysics starts at On request and FreeCAD at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, COMSOL Multiphysics or FreeCAD?
FreeCAD has a free tier; the other does not. Paid plans start at On request for COMSOL Multiphysics and Free for FreeCAD.
Does COMSOL Multiphysics or FreeCAD run on more platforms?
COMSOL Multiphysics runs on Windows, Linux, macOS. FreeCAD runs on Windows, macOS, Linux.
Can I use FreeCAD for free?
Yes. FreeCAD has a free tier, so you can try it without paying. COMSOL Multiphysics starts at On request.
What is COMSOL Multiphysics best used for?
COMSOL Multiphysics is most often used for modelling a device where physics are strongly coupled, such as induction heating that changes material properties which change the field, research work needing custom partial differential equations that no packaged solver in a mainstream tool provides, packaging a validated model as an app so process engineers can run studies without learning the simulation tool, a department wanting shared concurrent access via a floating network licence, with cluster runs at no extra licence cost. Of those, modelling a device where physics are strongly coupled, such as induction heating that changes material properties which change the field and research work needing custom partial differential equations that no packaged solver in a mainstream tool provides are not what FreeCAD is typically brought in for.
What can COMSOL Multiphysics do that FreeCAD cannot?
COMSOL Multiphysics covers Coupled multiphysics solving, Equation-based modelling, Add-on module library, Application Builder. FreeCAD covers Parametric modeling, Part design, Assembly, Drafting.

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.

FreeCAD: How much does FreeCAD cost?

FreeCAD is completely free with no licensing fees, vendor lock-in, sign-up requirements, paywalls, or restrictions. The software is open-source and available for anyone to use and adapt.

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.

FreeCAD: Does FreeCAD offer optional support or sponsorship?

FreeCAD accepts voluntary donations to support the project. Sponsorship tiers range from $1 per month (Normal Sponsor) to $200 per month (Gold Sponsor), with different visibility levels. One-time donations of any amount are also accepted.

Source
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.

COMSOL Multiphysics: Is pricing published?

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