Caedium 5.2 for Mac was available as a free download on our application library. The program lies within Design & Photo Tools, more precisely 3D Modeling. The actual developer of this free Mac application is symscape.
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 FRS Coloring Book Volume 2, FbxConverter or LightWave3D, which might be related to Caedium.
