Hi

Fisrt off all i want to tell that i am not an experience user..
The software dont belong to me... but in the company i work

The problem :.

I download a free car model  in solidworks format  .sldprt

i saw some tutorials about cfd analysis  and try to make cfd analysis from simple objects i created in 3DS  (imported as a wrl )

Now when i open the sldrtp file of the car model  the scan says that has nothing bad surfaces

i open the cfd wizard and make the adjustments

But after cfd Analysis... when i open to see the results..   all the lines of forces pass through the model.. not over it..

why?

i will post later some pictures of the problem..
