I'm slogging through the Numerical Basis of CAD-Embedded CFD White Paper
Quote:
Mesh generation is started by dividing the rectangular computational domain into a set of
rectangular cells (cuboids) formed by intersection of planes parallel to the axes of coordinate
system. The mesh can be refined (by splitting each cuboid into 8 geometrically-similar cuboids)
using various adaptation criteria that can be defined for each solid body (curvature, narrow
channels, small features, etc.) and automatically according to gradients in the solution.

It sounds like they're talking about voxels and dynamic subdivision.

New Maxwell Render plug-ins announced for SolidWorks, Rhino ... - DEVELOP3D
The SolidWorks release features updates to Maxwell Render 3.1.1 binaries and support for OpenVDB (i.e. Volume File) to Volumetric extension. Fixes include resolving the colour param that failed to work properly in the Transparent material type, and viewport materials that were not updated on some types of changes.

A free plug-in for Solidworks that incorporates OpenVDB, but at the rendering stage? Does it help with iterative calculations?
