Hi....

this is my first attempt at any CFD so I'm hoping this will be an obvious problem to some of you more experienced minds. Also I have tried a search of this forum and google but haven't yet found an answer so any advice would be greatly appreciated.

Basically I've made a model of a race car GT wing in CATIA V5 and I want to run some analysis in Star CCM. I watched this tutorial http://www.youtube.com/watch?v=OGIYYLziZWI and followed it to the letter but everytime I try to create the surface mesh I get an error saying that I "have patches that partially overlap" and that this "is not allowed while surface wrapping".

Now I was under the impression that the point of the surface wrapper was to make it easy to convert a CAD model to CFD quality.....but I'm not finding it so

If it would help anyone answer my question I can zip the file and attach it.

Thanks in advance for any advice offered.
