The short version

  • Each has a real cost: Inventor pricing shown as template variables on the page, suggesting dynamic or region-specific pricing; 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.
  • They diverge on capability: Inventor covers Parametric modeling, COMSOL Multiphysics covers Coupled multiphysics solving.
  • 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.

Inventor

  • Mechanical designnot COMSOL Multiphysics
  • Product developmentnot COMSOL Multiphysics
  • Manufacturing documentationnot COMSOL Multiphysics

COMSOL Multiphysics

  • Modelling a device where physics are strongly coupled, such as induction heating that changes material properties which change the fieldnot Inventor
  • Research work needing custom partial differential equations that no packaged solver in a mainstream tool providesnot Inventor
  • Packaging a validated model as an app so process engineers can run studies without learning the simulation toolnot Inventor
  • A department wanting shared concurrent access via a Floating Network Licence, with cluster runs at no extra licence costnot Inventor

Where each one falls short

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

Inventor

  • Pricing shown as template variables on the page, suggesting dynamic or region-specific pricing
  • No clear pricing information readily available on the overview page

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.

Answered from the vendors’ own pages

Inventor: How much does Autodesk Inventor cost?

Autodesk Inventor pricing is not displayed on the overview page. Monthly and annual subscription options are available, including single-year and multi-year terms. Customers can access pricing through their Autodesk Account or contact sales.

Source
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.

Inventor: Is there a free trial for Autodesk Inventor?

Yes, Autodesk offers a 30-day free trial of Inventor. You can start your project and try the software for free during this period.

Source
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.

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.
