CFD: merry christmas blender suzanne

[thschrader]

There is a competition on youtube:
https://www.youtube.com/watch?v=lBG3qphtofE
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.

...and some mesh-statistics:
I think the mesh is still too coarse for turbulence-modeling.
Runtime calculation more than 4 hours on my laptop.

I am just curious about the software you use to create the equations as the last image? I have seen similar ones in the forum (maybe always posted by you?)

Hi JV_3D,
the turbulenceData-pic is a smath-studio file:

(rename file to monkey.sm)

The checkMesh-pic is the data given when running the "checkMesh" command in the
bluecfd-terminal. bluecfd (=openfoam-clone for windows) is needed for using
the cfd-of-wb in FC.

Thank you so much

SmathStudio looks pretty cool, it could help me with some equations I need to show
