Currently I'm working overseas from where the car is and we wont be back there for some time so I'm dealing with the enforced separation by working on the body design and finalizing everything else anything else I can think of.

To that end I'm trying to get a proper understanding out of the use of openFOAM to do CFDanalysis of the various ideas i have for the body shape and get some idea of what does / doesn't work.

OpenFOAM by the way is open source so free to download - use, you just need to put the effort into learning the thing. The learning curve on the software I've found steep, and the resources available limited.

What I've not found is any other like minded people such as myself specifically interested in the the automotive application of the software that are willing to talk / share information on how to get reasonably good and reasonably reliable results from the software.

The only form to date I've found of any use is http://www.cfd-online.com/ which is useful to search but not so good for the noob questions.

So if anyone out there is attempting the same as myself or can point me at a forum more suited to the task that'd be great.

For your entertainment a video created from a recent run: http://www.youtube.com/watch?v=I3eMq0quJwo

Can't help with your question as I am almost 'puter uilliterate but as for your vid. . . Now that was cool.

only for ubuntu and linux though?
can't find any windows downloads

I'm running the blueCAPE Windows port. Which costs I think 50 Euro to buy and worked for me out of the box once I gave it sensible commands.
Or you if you're a masochist you can recompile it yourself on Windows.

The command line to drive it is still Unix type commands, but that's not so hard to get used to (Easy for me to say now I've done it I know).
The settings for the program are mainly in plain text files, just understanding the Unix batch files to start the whole thing took a bit of getting used to.
