The short version

  • Only D5 Render has a free tier, so it costs nothing to try first.
  • 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.; D5 Render windows-only application with no macOS support
  • They diverge on capability: COMSOL Multiphysics covers Coupled multiphysics solving, D5 Render covers Real-time ray tracing.
  • 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.

D5 Render

  • Windows-only application with no macOS support
  • Requires dedicated NVIDIA GPU, limiting hardware compatibility
  • Community edition restricted to non-commercial use only
  • Teams plan at USD 75/seat/month becomes expensive for larger organizations

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.

D5 Render: What is the pricing for D5 Render Pro?

D5 Render Pro costs USD 38/month or USD 360/year. Annual billing saves 20-21% compared to monthly payments.

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.

D5 Render: Is there a free version of D5 Render?

Yes. D5 Render Community edition is free for non-commercial use. It includes the full rendering engine with real-time ray tracing, unlimited projects, and approximately 2,000 library models and materials.

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.

D5 Render: Does D5 Render work on macOS?

No. D5 Render is a Windows-only application that requires a dedicated NVIDIA GPU. There is no Mac version available.

COMSOL Multiphysics: Is pricing published?

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

D5 Render: What are the output resolution capabilities in Pro?

D5 Render Pro supports 16K stills and panoramas, 4K video, frame sequence rendering, and VR output with full Showreel capabilities.
