Hey thanks for some ideas guys! This is a motorsport, so I figured this was a good spot for it. I only have the AutoCAD 2002 file of the car. How can i convert it to SolidWorks?

As for the sprocket, we have gone with a large one because during the race, they want us to stay under 30 mph. The way we run the race is that we will run the car up to about 30, then cut the engine and coast as long as possible. Then around 5 mph, we would restart the engine and get back up to 30 as quickly as possible. We figure that the larger sprocket gives us a shorter burn time, saving fuel. The tires are 21"d 130 psi bike racing tires that seem to perform pretty good. Thanks for the great feedback guys.

HI )) No problem))
Email me some files)) i can said whether my SW understood it or not))))


SW can read
sldptr, sldasm, slddrw
prt, sldprt,
asm ,sldasm,
drw, slddrw,
dwg,
lfp, sldflp,
prtdot, asmdpt, drwdot,
x_t, x_b, xmt_txt,
igs, iges,
step, stp,
sat,
vda,
wrl,
stl,
cgr,
ptr,xpr,
asm, xas,
Ipt, par

such TYPE of files SolidWorks can read))
Save you detail in such format)) or send it like Autocad files))


GL you ))) best regards))

phys.msu@gmail.com it's better recive big files))))))

Hello.I've the new updates are published on the next link I've change
the cross section and make curved end plates And the notch
Pleas tell me about any notes

good job))

but 1 question

Surface area [m^2] total 1.16961 x= -0.00171764 y= 0.00125173 z= 0.00241697

How it possible to have negative area??

This front wing tests are a waste of time because the front wing is under the effect of the ground, not considered in the tests.

[Guest]

Yep m8



now loking for boundary conditions for front wing
looking such button in Floworks to set "ground effect"

didn/t do this yet

Hello
First I would like to thank stik for his post and any one who tell me
about my mistakes . Second the problem is about seting the velocity to
be zero at certain distance (about 15 cm) under the wing to get the
ground effect. actually i don't know how to get this with floworks
untill now but I'll try to find the option for it maybe it can be wall boundry
condtion I think

Hi all(( it was my post((((( but i was sure that logged in

Hay take a look to this link

I agree if my results come to publicity

Fluent.com Not so bad Front and rear wings
Next my work wll be suspension See it after 1 week in fluent

CFD in SAE has been done for a long time. I did this in 2002

Do you have any images of the grid used in Flowworks? It seems very coarse!!. What turbulence model are you using?

To model the ground, put in a ground and set the shear stress to zero or define a motion on the surface if that is possible

Sure )) mate )) it was joke)) Sorry if somebody have some bad time.... but was realy joke))

Yes I looks this way cause i pain tit plots useing 32 colors gradation)))))) cause when you use 32 000 000 it not so undestandile))))) where is borders))
About models i was ( as i remember)Adiabatic wals, non grav efects, and the last one ))

To use ground effects, put the edge of the domain at ground level, and then set it to symmetry.

It's also important to model a tire when doing front wing CFD. The airflow off the endplates should be interacting with it.

Hey, I am going to use SolidWorks and Floworks to design and test an F1 car for the Jaguar F1 in Schools Challenge. If you need to get a legal copy of Solidworks and Floworks, I found them both for $150 (educational version, but it is the exact same) here http://www.journeyed.com/itemDetail.asp?T1=36835643+FS6.
Also, could somebody help me in determining the drag of my model in Floworks? Thanks.
