wind tunnel

Lets see what contribution this turns into...

as i was trying to evaluate a drag coefficient for a simple shape... i found CodeSaturne, after same trouble to get it working, and with a little help from my friends..

This wind tunnel was made to work with CodeSaturne (1.4a) in CaeLinux 2009,

I used solid works to generate a simple shape (cylinder 1 meter diameter by 1 meter long, this way its easier to calculate projected areas). saved in a step file.

this file was imported in SalomeMeca, and a mesh file was generated. both files will be uploaded.

then started ./SaturneGui, (i assume you know how to cs_creat a study) and defined my wind tunnel, as simple as possible. xml file will also be uploaded.

i made sure the mesh file and the usproj file were in the right places. /MESH and /SRC.

output will be placed in user /tmp directory. also i will upload my results, for comparison only. although i think it hasn't converged...

the core part is the usproj file, this was kindly supplied by Mr JamesMcNaughton. here: http://cfd.mace.manchester.ac.uk/twiki/bin/view/Forum/ForumIntro0042

I made a few changes to get the forces for drag and lift. having the projected area and a little knowledge of fluid dynamics you will fin the Drag and lift coefficients.
