Needed: CFD analysis on a SolidWorks assembly drawing

[Cd]

Blue Bomber Man, you are of course aware of all of the free open-source CFD software out there aren't you ? "thumbs-up"

( I'm not good with math, so I just do 3D modeling.)

Actually I am not aware of any program that will take a 3d cad program file and do a CFD analysis, but I would love to learn of some, thanks!

Yes, do tell us about the free CFD software. I've been utterly unable to find any.

I whipped up the attached in SolidWorks today. It needs fewer lines and more radiused edges, and then there are aerodynamically important complexities such as a radiator, suspension, &c. Without a radiator and a full engine bay, how will I know whether to build a variable-geometry grille?

I don't have FlowWorks, but I would love to run several models through the CFD analysis: the attached model, three with nose-cones of three different heights, and one with a boat-tail. That would determine how effective these aero add-ons would be, and whether to try to send air over the car or under it.

I'd be happy to make my .SLDPRT files available in the public domain. Anyone know of a good, free .SLDPRT of an engine, radiator, or maybe even a sophisticated model of a car?

Robert,. have you Googled "open source CFD software" ?
There is quite a selection .

[RobertSmalls]

Hmm, I see that there is. Can anyone recommend an easy-to-use one that I can feed a SolidWorks or Pro/E CAD drawing into?

I should add I am a beginner, so if you let me know exactly what you need doing I'll be happy to give it a go.

Dave do you still have access to flowworks, I have an autocad of my car and would like to know how it performs in flowworks.

If you can create a 3D model in Solidworks from your Autocad then I'll see if I can run it through the analysis. It's been a while since I used it

Exactly. And nothing changed since you used it last time

Huh?
