LFS Physics

[Blowjohn]

Hi

I'm a Biomedical Engineering student working on a model of the head/neck
subjected to frontal and lateral accelerations . I heard you developed
great physics in your game and I was wondering if it was possible to
extract the various components of the acceleration in order to validate
our model in a "real" situation (for the car's center of gravity).

I thought it would be a great way to test-drive our model in a car without
hitting the tracks, it's less dangerous :). Is it in any way possible for
you to output (to a file?) the accelerations that would affect the
head/neck portion of the body?

We could then read the output file with Matlab and see if we have indeed a
model that works according with the driving in the game.

I hope you can consider helping me.

I thank you in advance

Take a look at the InSim documents in LFS's doc's directory, particularly OutSim :)

I think for this application OutSim is the way to go. I never tried making a connection to OutSim, so Im not sure if I can really help you with that.

In-game you can make the POV have a certain displacement for each g you get, so I guess the accelerations on the head are calculated.

Maybe it would be a wise thing to mail Scawen (scawen at *NOSPAM* liveforspeed dot net).

If you need the data for post processing (no live values while driving), the telemetry feature is the way to go. Just drive some laps, hit escape, watch the replay and extract the telemetry data. Various values including acceleration are then stored in a .raf file which can be read with replay analysers like F1PerfView (http://www.xs4all.nl/~rsdi/f1perfview.html). This tool can export the data to csv or txt files so you can import it directly into matlab.

You will get the accelleration for the car, though, not the head.
