Hi,

it is a while that I don't have done CFD runs for the Ahmed Body. Nevertheless, most of the time I use the fvSchemes and fvSolution files of the motorbike tutorial. These files are located in the following directory:

OpenFOAM-1.7.x/tutorials/incompressible/simpleFoam/motorBike/system

Regards,
Stephane

Hi OF-users,

can someone summarize the experimental data Cd and Cl for the Ahmed body with the different slant angles.

it is also worth to indicate the undisturbed air speed and kinematic viscosity of the air.

best regards,
Stephane.

Move over Ahmed. There's a new new reference in town.
Its called DrivAer

discussion
http://www.aer.mw.tum.de/en/research-groups/automotive/

more discussion about the models
http://www.aer.mw.tum.de/en/research...otive/drivaer/

even more discussion with an email to request the models in IGES or STEP format.
http://www.aer.mw.tum.de/en/research...vaer/geometry/

a paper with CD and other info

Let the openFoam case files begin to flow

Congratulations!!!
This work is gold for CFD benchmarks!
Well done again!

this looks very very interesting!!

I would be happy to create some meshes and try some computations

Please do. It would be great if we had a case set up for moving wheels and such.

I sent an email to request the model to the email found on this page:
http://www.aer.mw.tum.de/en/research...vaer/geometry/

or if you can maybe send me directly this model, that would be great!

ConnClark · October 15, 2012, 13:21

I haven't gotten that to getting the model yet. I wanted to share the news as soon as I found it.

ConnClark · November 13, 2012, 14:57

Has anybody heard from these people when requesting a model ? I have had no response.

ConnClark · November 13, 2012, 18:12

It might help if I didn't type in the email address wrong :P

Edit : With the right email address I got the model I was after in STEP format. I'm going to convert it to STL in FreeCAD.
