What do you think about Blender? I think the key to economical CFD is support for OpenVFD. Which Blender has. And particle systems that can create fire, smoke, water droplets, etc.
Plus all the animating, compositing and video editing you could ask for. Apparently it has intimidated me. I'm stuck at 3D modeling, but I like the node-based editors for everything.
Rebodied Model T?
I'd conserve the Ranchero/Nash/Hudson, but hey....
