Caedium 5.2 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The application lies within Design & Photo Tools, more precisely 3D Modeling. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe.

From the developer:
Caedium (formerly SymLab) and its add-ons combine to form an easy-to-use Computational Fluid Dynamics (CFD) software system that can help you assess the performance of your 3D model.
Using Caedium add-ons you can create any 2D or 3D geometry or import your geometry from another CAD package.
You may want to check out more software for Mac, such as Realsoft3D, FRS Coloring Book Volume 2 or FbxConverter, which might be related to Caedium.
