The short version

  • 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.; Redshift no specific pricing amounts published on product page
  • They diverge on capability: COMSOL Multiphysics covers Coupled multiphysics solving, Redshift covers GPU rendering.
  • 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.

Redshift

  • No specific pricing amounts published on product page
  • Only 14-day free trial duration mentioned; no longer-term free tier
  • Must contact sales team for subscription cost details

Does COMSOL Multiphysics or Redshift run on more platforms?
COMSOL Multiphysics runs on Windows, Linux, macOS. Redshift runs on Windows, MacOS, Linux.
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 Redshift is typically brought in for.
What can COMSOL Multiphysics do that Redshift cannot?

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.

Redshift: What is included with a Redshift subscription?

Redshift Subscription includes all integration plugins and capability for multiple instances up to 8 GPUs on a single computer. Specific features beyond rendering engine not detailed in public pricing documentation.

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.

Redshift: How long is the Redshift trial period?

Redshift offers a 14-day free trial for users to evaluate the software before purchase commitment.

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.

Redshift: Where can I find Redshift pricing details?

Specific pricing is available through Redshift store access or by contacting the sales team directly. Pricing amounts are not listed on the public product page.

Source
COMSOL Multiphysics: Is pricing published?

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