COMSOL Multiphysics

Finite element simulation built around coupling physics, with add-on modules licensed separately

As of 31 August 2026, COMSOL Multiphysics's pricing is not published; the vendor quotes on request. A general-purpose simulation environment whose point is solving several coupled physics at once, such as electromagnetics heating a fluid that deforms a structure. Softwr lists it under CAD. COMSOL Multiphysics is made by COMSOL AB, available on Windows, Linux, macOS.

Overview

What COMSOL Multiphysics does

COMSOL Multiphysics is a finite element package covering structural mechanics, heat transfer, fluid flow, electromagnetics, acoustics, chemical reaction engineering and more. Models are built in a single environment with a common geometry kernel, meshing, solvers and postprocessing, and users can write their own partial differential equations directly rather than being restricted to prepackaged physics. The Application Builder turns a finished model into a form-based app that a non-specialist can run, deployable through COMSOL Server or Compiler. The distinguishing capability is genuine multiphysics coupling. Where most tools solve one domain and pass results to another, COMSOL assembles the coupled system and solves it together, which matters when the coupling is strong: induction heating, electrochemistry, piezoelectric devices, microfluidics with heat and reaction. That is why it dominates in research and in device physics rather than in mainstream automotive crash or aerodynamics work. Buyers are R&D groups, universities and device manufacturers. The trade-off is the licensing structure and the compute reality. The base product does not include the physics most people came for; each module is a separate line item. Licences come as CPU-locked, Named Single-User, Floating Network, and academic Class Kit variants, with Floating Network the only one that shares concurrency across a group and which includes cluster and cloud use at no extra charge. Perpetual licences include updates and support for twelve months and then renew at 20% of the then-current price annually, so the maintenance bill compounds as the module list grows. No prices are published anywhere on the vendor site.

What people use it 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

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about 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, with sources

Questions people ask

Each answer names the page it came from, so you can check it rather than take our word for it.

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.

What does maintenance cost?

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

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.

Is pricing published?

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

Softwr does not host reviews and shows no star rating for COMSOL Multiphysics, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
