no wonder my rear bumper is the dirtiest part of the car, very cool images, keep the info rolling!

 

I was going to say something about that. So THATS why we have so much dirt accumulate on the rear bumper

Also, never drive a station wagon with the trunk open as it sucks the exhaust gases back into the car. Carbon monoxide is poisonous the last time I checked

I am going to try a top down, window up version next. Give me a few days...this thing is a BEAST to run. I have a 4 gig machine and it ran it out of memory the other day

 

Cool. You definitely captured some of the important aspects of the flow that I would expect to see, so this is getting more and more realistic. Nice work.

I run ground vehicle stuff on a cluster of four dual-CPU Apple G5 machines, with a total of 20GB RAM. Sometimes that's not even enough!

I am jealous. We are about to release a 64-bit version of the software that will support 16 GB on one machine. Shortly after that we are releasing clustering. So you could theoretically set up ten or twenty top of the line 64 bit machines and have a small supercomputer

Does anyone want to see anything in particular? Like I said, my next model will be top down, windows up. I'll model the roll hoops and wind deflector too. Maybe a supercharger assembly w/ aftercooler for some internal flow action.

 

The data from that latest model:

Velocity 120 mph
Drag 321.45 lbf
Downforce 9.46 lbf
Drag Coefficient 0.43

The symmetric nature of the model is resulting in slightly higher than normal drag forces. I suspect a full model would produce 10-15% lower drag numbers and a coefficient of around 0.36

 

I always like to see mesh pictures, maybe one of the body and another of the symmetry plane.

Pretty mesh pictures for your viewing pleasure. Note the mesh enhancement at the fluid solid interfaces

 

WOW this is very useful thanks for posting this info.

 

Awesome! Can't wait for the next step.
