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.; MoI (Moment of Inspiration) it is developed by one person, so releases are years apart and there is no support organisation to escalate to when something blocks your work.
  • They diverge on capability: COMSOL Multiphysics covers Coupled multiphysics solving, MoI (Moment of Inspiration) covers Direct NURBS modelling.
  • 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.

MoI (Moment of Inspiration)

  • It is developed by one person, so releases are years apart and there is no support organisation to escalate to when something blocks your work.
  • There is no parametric history and no assembly structure, so a late design change means remodelling rather than editing a feature.
  • It produces no dimensioned drawings or manufacturing documentation, so anything heading for production needs a second package for the paperwork.
  • Exchange is limited to surface formats such as STEP and IGES with no native interoperability with mainstream MCAD systems, so it sits at the edge of an engineering pipeline rather than inside it.
  • Each major version is a fresh purchase, and the long gaps between versions mean a fix or a feature you need can be several years away with no interim release.

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.

MoI (Moment of Inspiration): Is it a subscription?

No. It is bought outright per major version, and each new major version is a separate paid upgrade.

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.

MoI (Moment of Inspiration): Can it replace Rhino?

For direct form modelling, often yes. For anything needing Grasshopper, drawings, plugins or engineering interoperability, no.

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.

MoI (Moment of Inspiration): Why do 3D artists use it alongside other tools?

Its NURBS to polygon conversion produces cleaner meshes than most CAD exporters, which saves retopology work downstream.

COMSOL Multiphysics: Is pricing published?

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