Caedium Add-Ons

  • Caedium is a single, unified, simulation platform where value-added functionality is provided by add-ons (e.g., RANS Flow).
  • Caedium Professional is a convenient way to activate all Caedium add-ons.
  • Without any activated add-ons you can use Caedium to view project files (.sym).
  • If the feature is not listed on the respective add-on product webpage then it is not supported.
  • The product webpage for the RANS Flow add-on has a section "Not Supported" to clarify unsupported features.


  • Caedium provides geometry manipulation, native meshing, solver control, and visualization, so it is much more than just a GUI for OpenFOAM.
  • A selection of OpenFOAM solvers act as the CFD engine within the RANS Flow add-on.
  • Using Caedium is not a good way to learn OpenFOAM, given that OpenFOAM targets Unix as a file-based command line CFD toolkit.


  • Caedium is a multi-platform system, running natively on Windows, Mac OS X, and Linux.
  • Within Caedium the OpenFOAM solvers also run natively in the background on Windows, Mac OS X, and Linux.


  • Caedium provides native meshing algorithms for tetrahedral, hexahedral, and polyhedral elements.
  • Surface mesh nodes are located on the true analytic geometry (e.g., NURBS) when available.


  • Online tutorials for Caedium are freely available.
  • The forums are open to questions from anyone with a free Symscape account.
  • Only Caedium Professional paid subscriptions have one-on-one technical support in the form of email, webinar, and/or phone.


  • Free 30-day trials are limited to one per person per computer.
  • Free trials are not transferable between computers.
  • Paid subscriptions are transferable between computers.
  • Caedium add-ons are only available as subscriptions (i.e., time limited).
  • Caedium is not available with a perpetual license.


  • Subscription rates are listed on individual add-on product webpages.
  • Feature and subscription rates are also listed on the Comparison webpage.
  • The longer the subscription period (1 month, 3 months, and 12 months) the lower the monthly rate.
  • Subscriptions are paid upfront in full for the entire subscription period.
