Correlations of simulations

Newey said:
“So, while the core structure is similar, it’s a big aerodynamic package coupled with significant weight reduction. The target is to get very close to the weight limit.”

The team principal, however, stopped short of putting a number to the revised car.

“We’re predicting a large step, but I’m reluctant to put specific numbers out there because our simulation tools aren’t yet as sophisticated or well correlated as they need to be.

“Historically, at this team, there hasn’t been enough investment in engineering simulation tools – not just project management systems, but the core physics tools themselves.

“We’re putting that investment in now, but you don’t rewrite and validate those tools overnight. Correlating them properly with the real car takes time.

“At the moment, they’re improving, but the real gains from that work will come later in the year.”


Can somebody explain what mean simulations are not correlated? Does this mean, CFD not showin correct numbers of downforce, drag etc or they mean simulator not show correct lap times?

Downforce and drag they validate from wind tunnel or ? Can wind tunnel also be not correlated?

How they fix this, they must change code of CFD solver?

I bet Claude Code could figure it out in a hurry... :mrgreen:

All models are wrong, some models are useful.
An uncorrelated model is just an opinion.
The fewer channels of data you give to me for correlation, the faster the correlation will go.
