Speed Skiing is a discipline where a skier tries to reach highest possible speed while going downhill in a straight line. Word record is 255.5 km/h.

One way to better understand the air flow around a skier, at such speeds, is to use virtual simulations, CFD. This is used to improve the pose and equipment (such as helmet, fairings, poles etc.)
Here we will look at a workflow using only free and open source tools and how Blender is the key part of it.
