Don't know.  Easiest is to research the file formats acceptable by the analysis software packages.  I just looked and Hum3d appears to export in many formats.

You probably could but you would need them as shell or solid models. Been a few years since I've dabbled with STAR-CCM+ but can remember the struggles of simplifying overly complicated parts. As long you can open it in a CAD software, then you should be able to convert it as needed.

Yes.  A lot of 3d solid modelers have a basic fluid flow application as well.

We have a front line 3D laser scanner, (Faro S70), which we'd be willing to deploy on this effort for very reasonable cost. Located in the PNW. I would be curious about using the model for some aero tweaks I have been contemplating. Perhaps I could scan my '72 if there'd be an interest in the full data set produced?

I could get in on this- split the cost and share the data?

 

STEP, IGES, something Solidworks-able?  Probably even an .stl...

Solidworks chokes on the amount of data produced by the scanner but we should be able to export in a manner friendly to the product. I am on out of town a project now so will check back in a couple weeks. I'd like to get mine up on a lift and get the undersides too.

Hey irdave I've been working with tii1on and the Faro scanner. Yes we definitely can get STEP, IGES, or other Solidworks compatible files. Lots of file options. Our best option would probably be a surface model like you mentioned because we have some nice software to help make it, but we can also give the raw point cloud data. Easy to reduce the file size so that Solidworks can handle the point volume, but of course this will reduce the resolution.

Nice.  I just tried working with an stl file, converting it to a solid.  Kind of pain.  But any solid that'll work in SW would be great.  The stl would be fun to print, but the solid to mess with for fluid / aero simulation.

 

Please keep me posted.

 

Thanks.

irdave, if you had access to some decent fluid modeling software, I'd have an interest in that. Perhaps a trade can be arranged.

 

Nothing special anymore.  Used to do some big work using Converge, but that was a while ago.  I was just going to use the flow simulator in Solidworks.  If you want to get into it a bit, Openfoam is open source and decent.

Hey guys,

 

What did you end up with as far as models and simulation results?

 

I am looking for the bottom view of the chassis for general geometry and subframe locations to mount an electric conversion. I have no experience in 3d scanning but am proficient in solidworks and have been wanting to tackle it with a 3d systems sense 2. I would imagine its tolerance is so loose compared to the Faro, but Im just trying to get some imported surfaces with accuracy up to .125" over the width of the car

I never got anywhere with it, but I'm easily distracted.  I'd imagine the Blue Book has all relevant dimensions for the chassis if you wanted to start with that...

Good Morning,

 

We got nowhere, actually, and have moved on from that equipment. We're no longer developing 3D models at this time. I would retain interest in getting my hands on an accurate model, though, if someone comes up with one.

 

Best,

Bryan

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
