Mclaren lost a lot of time fixing their brake issue. They were 4-6 sessions behind.

Once Mclaren brake issue was solved they tweaked their setup, which was more on target than Merc.

Merc has said they know the simple solution to stop the porpoising, but it won't allow them to compete for the WCC. They look to be adamant on making the bold design work.

Is the CFD/Tunnel time set at mid-season? I'm still a bit confused when they rank everyone.

I've decided to look at this as a glass half full guy.

While K MAg lost 4 spots today, the fact that he was running mediums while everyone else was on softs tells me they got a hot rod under his arse.

Still doing a rain dance, but I think the Haas will be in good shape in the dry as well.

Is I recall, yes. Mid season and end of season I believe.

finishing farther down gets them wind tunnel and CFD time (which they do need)

So #TankForCFD?

How is CFD time even tracked by the way? What prevents a rogue engineer from taking data on a thumb drive and running CFD simulations on a pirated copy of Ansys or whatever software they use in his basement? Is it the actual wind tunnel time and subsequent data analysis from the data gathered that's restricted? I am confused. :shrug:

If I understand correctly there are two times this is set based on the end-of-season rankings and the mid-season ranks. It is a twice-a-year thing.

I've wondered this as well. I'm guessing the computers used for F1 level CFD are probably bigger than you can pick up at Best Buy or something.

And what is to stop Haas from renting the windtunnel in NC for some clandestine testing.

*With the Nascar mandated bodies they probably don't do much wind tunnel work anymore. Otherwise Gene could easily invoice some F1 tunnel time to Stewart-Haas.

They are allowed a certain amount of terraflops. Teams are required to submit the hardware specs and data output. FIA can audit the data to determine if the data could indeed have been performed on that hardware in that amount of time.

quote:

Each Team shall report to the FIA details of its Restricted Wind Tunnel Testing and Restricted CFD Simulations for the preceding Aerodynamic Testing Period within 14 days of the end of that Aerodynamic Testing Period. The data must be provided in the exact format specified by the FIA, details of which may be found in the Appendix to the F1 Technical Regulations.


quote:

In order to check on the hardware employed by the Teams and as a means of assuring common application of the restrictions set out in this Appendix, the FIA will arrange for independent benchmarking inspections of both Wind Tunnel and CFD activities to be carried out from time to time. Recommendations arising from these inspections will be incorporated into this Appendix.


quote:

The amount of compute resource used for the solve part or parts of all Restricted Computational Fluid Dynamics (RCFDs) shall be measured in Mega Allocation Unit hours (MAUh) and will be calculated as follows.

AUh = (NCU * NSS * CCF) / 3600
NCU=Number of Processing Unit cores used for the solver run.
NSS=Number of solver wall clock seconds elapsed during the run
CCF= Peak Processing Unit clock frequency in GigaHertz achieved during the CFD solverrun


I don't think the regulations are entirely bullet-proof and it still seems somewhat like a "gentleman's agreement," but it does prevent the "employee running it at home" scenario.

Note, I had to research this just now. I had also always wondered this.

ETA: I see some web pages saying FIA has cameras in team wind tunnels and can remotely view the computers for CFD. No one has listed sources, so maybe it's true, maybe it's not. I know if I had millions on the line and FIA had a camera on my wind tunnel, then I'm printing out a picture of an empty wind tunnel and putting it in front of the camera

CFD time like wind tunnel time is logged. It is third party audited. If you show up with a new aero part you have to be able to show your work from conception to reality. If you show up with a new floor and can't provide Ross Brawn with the step by step process of how it came to be you have a problem. If a team is making a big leap that has no logged CFD or wind tunnel time to support that leap then you have a problem.

Copying someone's homework at the local copy shop is not acceptable support for "your" new idea.

In today's world, an idea going straight from the drawing table of Adrian Newey to a carbon fiber bit on the car just doesn't happen. If it does happen then chicanery is assumed.

Sonic looks a lot different in Italy apparently.

Any CFD done on the physical scale of an F1 car isn’t being done on a normal desktop. It’s being done on some sort of High Performance Supercomputer either owned directly by the team, or the CFD time is rented from another company that owns a supercomputer.

At one time, Haas was renting time from Corvid Technologies in Huntersville, NC. Not sure if they’re still doing that or not though.

Teams that own their own supercomputers are in a much better opportunity to ‘fudge’ their CFD numbers.

I guess, will just have to take you at your word, then? Who did you take your Heat Transfer and CFD classes at LSU with - Prof. Keith Gothier, Prof. Sumanth Acharya?

But that is impossible:




All good things have to come to an end and then you have to suck it up and eat the shite sandwich. It is just part of being a sportsman or being a sportsfan.

I like how Christian and Toto are about as far away as they could have gotten from each other.

The first thing I noticed was how Zak just rolled up straight from the paddock looking like he was headed to Hooters.

I wonder if Matty and Christian will be sitting so close come November.
