But emotion doesn’t play THAT big of a part in car purchasing!

*ahem* JEEPS

house brick would be less aerodynamic than a Jeep

What I wouldn't give to run a few simulations like that...

Its a joop thing, you won't understand

They’re not particularly hard simulations to run, takes a long time to get usable results, but you can get an image like the ones above in just a few minutes.

Kinda an apples to oranges comparison. Different softwares, different flow mediums, different settings. Of course the Jeep is not very aerodynamic, it just annoys me when this image goes around and doesn't really give a fair comparison.

The jeep shows streamlines instead of local vectors. So it’ll always look more chaotic.

However, the streamline does look like air flows through the radiator, past the engine, hits the firewall, swoops outside of the bodywork, into the window and smack into the driver’s face.

But how many thousands does the software  cost?

A cow in a wind tunnel...not fucking likely.

Maybe nothing?

Not sure of the exact capabilities, but there are screenshots that look about right...

Autodesk Flow design is available with a student license, and since unsupported so cheaply accessed. Solidworks simulation also can do fluids. I know Fusion can do static simulations, not sure if it can do fluids.

Im also pretty sure Ansyis is free to use if you don’t use it for commercial uses. Harder software to use though. Can definitely get images like these from open source or free for hobyists software though.

Have a cad file of something you want tested? Be happy to run it for you.

What file format of models can it take?

Been a little while since I've run one, but I think I used .step or maybe even stl. Any file is pretty easily convertible these days.

That’s for if the heater quits working
