The key to low-compute-power CFD IMHO is OpenVDB:

OpenVDB includes a small number of Maya nodes, primarily for conversion of geometry to and from OpenVDB volumes and for visualization of volumes. This archive contains several example scene files that demonstrate how to use the nodes. Maya Examples zip - Aug 8 2016

It's all about the sparse inverted B-trees, if ya know what I mean. And being able to attach arbitrary attributes to each voxel. If you need it, the odor of hickory smoke.

Instead of computing every voxel in the virtual wind tunnel, it looks more diligently closer to the aeroform.

It's above my pay grade.
