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.; DraftSight specific pricing amounts not disclosed on website
  • They diverge on capability: COMSOL Multiphysics covers Coupled multiphysics solving, DraftSight covers DWG/DXF support.
  • 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.

DraftSight

  • Specific pricing amounts not disclosed on website
  • Directs customers to contact sales or visit store for pricing
  • Three tiers available but feature differences not fully detailed

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.

DraftSight: Is there a free trial for DraftSight?

Yes, DraftSight offers a 30-day full-featured trial available for download. The trial provides complete access to all 2D/3D tools and advanced features.

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.

DraftSight: What DraftSight tiers are available?

DraftSight offers three pricing tiers: Professional (core 2D CAD tools), Premium (adds advanced tools, STEP import, and BIM module), and Enterprise (for large organizations with multiple sites).

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.

DraftSight: What licensing options does DraftSight provide?

DraftSight offers Named-User Licensing for individuals and dedicated workstations, Network Licensing for shared access across users and locations, Perpetual Licensing for one-time purchase, and Cloud and Remote Access options.

Source
COMSOL Multiphysics: Is pricing published?

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