There is only 1 person who know the algoritms behind this - and because he didnt get any help inside the iRacing forum when he wanted it he from then on refused to make the code public.
He only from time to time accepted to calculate the grip values of some telemetry files PMed from some of iRacings pro drivers.
Is there a formula to calculate the grip generated by a tyre on a vehicle for a given surface? I have a 13,000 kg machine pulling nearly 200 N of weight. I need to figure out if we need to put any...
.csv export is in the making. It will be a part of the "pro" package.
The formula editor will be availiable soon as well, here is a first glimpse. It can be used to create such calculations as the grip or something similar. In the example below it´s a rather simple formula where the pressure difference between intake and discharge side is calculated.
Until now I have taken your questions rather serious - and have given you reasonable serious answers.
But this time your answer that calculation of grip (in racing simulations) is no secret - and you furthermore post a completely irrelevant link to some (again completely irrelevant) discussion where a bunch of engineering guys make fun with a guy who ask about how to calculate grip for a 13 ton "thing" pulling another "thing" with a force of 200 N.
Absolutely nothing in this link can be used to calculate grip in ANY racing sim - and by suggesting this you only does reveal your knowledge conserning both definition and calculation of grip in such a sim.
ByTheWay: If calculation of grip in a racing sim was/is no secret why has nobody exept one person being able to do it?
If you dont know this tool yet - https://www.simracingdata.com is a tool that keeps track of all your laptimes and telemetry.
Its even possible to view live telemetry in browser while someone is on track:
