Title: CFD - AirShaper.com
Post by: Simspeed on April 30, 2019, 04:02:20 PM

Hi...I'm considering using Airshaper.com to run a CFD simulation for my liner body design.  Has anyone used them before or heard any results or opinions from someone who has?  What other CFD services have been used by forum members that you'd recommend for a concept shape study?  Thanks...Terry

Woody at "Design_Dreams@cinci.rr.com" can do whatever you want with CFD.

Who's never (I think) shown us what he's working on.

Curious minds want to know.  Even some of us slower minds do, too.

What do you want to know?

If you want absolute force values I wouldn?t trust anything but full vehicle transient modeling, and even then I wouldn?t trust it without windtunnel and coast down correlation.

If you just want Delta?s of part changes then the nature of the part and it?s place will have an influence on the choice of cfd modeling.

I?m afraid there is no easy answer. People dedicate their entire careers to trying to figure this stuff out (myself included). Unfortunately many racers like to believe the first or cheapest answer they get, which is often misleading or just plain wrong.

I?ll be at Bonneville over the first weekend this year (unfortunately we can?t race this year), seek me out to talk (too much info for a thread). PM me for my cell number, that?s an open invitation to anyone.

Advice is free, implementation will cost you 😉
