There is a competition on youtube:
Calculate the drag-coefficient of blender-suzanne.
I got cf=1,85. But my calculation is invalid, because I redesigned suzanne..
The original stl is broken (eyes are not attached to head). You can fix it easy
with netfabb basic, but I wanted to use FC alone. Another Problem: the stl has more then
50000 facets, even if you can convert it to a watertight solid, you have the difficulty to
adress the facets in the boundary-dialogs.
FC-file on my dropbox 2,3 MB:
