Can cause discrepancies between model and reality

The track parameters have an influence on the simulation results and can therefor interfere with establishing a good correlation between model and reality.

In the shown example, there are two track parameters which influence the model building process: wind and banking.

By adding 5 km/h of wind, we were able to get the speeds close together in both directions. This can be seen in the zoomed areas on top of the plot. On the right side you can compare with the results without any wind.

The other track parameter which influenced the results is banking. Both in corner 2 as well as in corner 5 experience about 6 degrees of banking.

In the bottom figure on the right side you can compare the results without banking in both corners.
