F1 in Schools help
 
Hi my name is Brett and i am involved in a program at school called F1 in Schools where we are required to design, test, manufacture and race a miniature F1 car. You are required to work in teams of 3-5 and you need to collect sponsors, have a portfolio showing everything that you have done, a verbal presentation and have a display booth on competition day etc.

We have won our state final and now move onto the national final which is being held at the Australian Formula One Grand Prix in late march.

I have been trying to do some CFD tests on our car to see what changes need to be made without machining it to test in the wind tunnel. Although i cant get fluent to work no matter what i do and the organisers have supplied us with a very basic version of phoenics that just lets us put in our model and get results from that. The only problem is I cant get it to converge properly so the results are never correct.

Here is a few pics of our car so that you can see what it is like

I know that this is a really big thing to ask but would anyone be willing to run a test on my model if i gave it to them and they would get recognition at the national final which will also get us more points for collaboration.

If not would anyone be willing to point out an easy cfd program to use or give me some step by step instructions for fluent.

Thanks
Brett

Caedium CFD Simulation
 
Hi Brett,

Thanks for sharing your geometry - here's a glimpse of the CFD results from Caedium Professional. For the full set of results try our rendered gallery.

Dear Richard,

What did you use for meshing the geometry? snappyHexMesh?
do you have some pictures of the mesh too? I didn't saw any in the link you give.

Regards,

Vincent

Mesh Details
 
Hi Vincent,

I used Caedium's native triangle and tetrahedral meshers. In total there were ~360K elements.

See the image below for a closeup of the surface mesh on the car, symmetry plane, and ground.

You'll also find a reference to the complete Caedium project file (.sym) there too.
