I think in cfd you can set certain surfaces to be outlets, so even though we haven't modelled the internal flow the simulation can be reasonably accurate. Also I have changed the model so the head support is now legal, thanks for pointing that outmachin wrote:Legendary M: How have you made your radiators? Are they solid (like mine)? If so it'll really screw up the flow around the sidepods in any CFD analysis as all the air from here will have to find its way around the pods rather than through them... the result will be a lot more drag and potentially more downforce from the part of floor infront of the pods due to high pressure here... I can't get to my other computer to look at converting my model until after the weekend, so it'll be interesting to see what these guys can do with the CFD analysis on your car.
(BTW your driver's head support is illegal; it needs to be chopped away to give the driver peripheral vision.... notice how yours has a smooth transition.. it should be quite bluff at the front). See diagram on page 59 of the 2009 rules.
Nice Model though! It looks like you've put in way more effort than me.. nice job! I knocked mine up in a few days!
If you want you can look at the model in 3d in a browser here:fabio999 wrote:Hey legendary M....what about the model?!?i would like to see it...to start thinking about how to mesh it!!and then to talk with you about what simulations we want to run!!
Let me know something then!!

The head rest area is quite highly prescribed within the rules this year. Undercuts as you describe (as featured on the Redbull last year) aren't allowed.....wesley123 wrote:Maybe around the headrest you can give those sides an vertical wing shape, just like red bull dis last year, then you undercut the insides for more efficient flow to the rear wing.
I believe TV cameras need to be aerodynamically neutral.ESPImperium wrote:Another idea i though about was, putting the TV camereas on the nose and the air box sides at a certain pitch thats advantagous to aero, say a 40 degree pitch to either give better aero efficency or generate altho small, some ammount of downforce. Allowing FOM only to use the T cam on the top of the air box for your car. Is that legal???
The FIA mandate the mounting positions and the maximum angle of attack, so you're highly restricted on that front I'm afraid.ARTICLE 20 : TELEVISION CAMERAS AND TIMING TRANSPONDERS
20.1 Presence of cameras and camera housings :
All cars must be fitted with either two cameras, two camera housings or one of each at all times throughout
the Event.
20.2 Location of camera housings :
Camera housings, when used, must be fitted in the same location as cameras. Details concerning the size
and weight of all camera housings may be found in the Appendix to these regulations.
20.3 Location and fitting of camera equipment :
20.3.1 All cars must be equipped with six positions in which cameras or camera housings can be fitted. Referring
to Drawing 6, all cars must carry a camera or camera housing in position 4, the position of the remaining
camera or camera housing will be determined by the FIA after consultation with the relevant Competitor.
Once positions are determined in the above manner, any decision as to whether a camera or camera
housing is fitted in those positions will rest solely with the relevant Competitor.
20.3.2 Any camera or dummy camera fitted in positions 1, 2 or 3 shown in Drawing 6 must be mounted in order
that its major axis does not subtend an angle greater than 5° to the reference plane.
