Wind tunnel model of an animated cyclist

The helmet was just an example, and yes the head can move a lot! I am interested in time-trial applications so think more about "aerodynamic" helmets. A static solution if accurate enough to detect the change between two different helmets (about 0.005 change in CdA) would be a good start.

Optimizing the shape bicycle shoes is another example and would be more complex to solve...

I struggle to define vertices adapted to my .stl file in blockMeshDict...

Bounds of my object are:

x range: -0.494534 to 0.498245 (delta: 0.99278)
y range: 0.996753 to 1.76781 (delta: 0.771054)
z range: -1.34513 to -0.209654 (delta: 1.13548)

How should I define the vertices in blockMeshDict given this?

Don't lose your time for this question, I found a very good tutorial that could help others here: http://www.wolfdynamics.com/wiki/mes..._blockmesh.pdf
