Hello
I have a question the the folowing Electric Engine Dyno example ( https://de.mathworks.com/help/sps/ug/electric-engine-dyno.html?searchHighlight=dyno&s_tid=srchtitle_support_results_1_dyno ).
I still don't get the choice of the step size, with which the torque input data were spaced considering the example's parameters?
does the choosen step size implies seconds or milliseconds?

Generally how do I now which step size between 2 input data does my model require, so that the results are accurate? is it just a step size or does it have a physical logique behind it (like each step size is a second or millisecond).
I don't seem to get the hold of it and I didn't find any helping documentation.
regards,

Click on Modeling Tab --> Model Explorer --> Base Workspace, and then you will see that the sampling time is 1E-5 in seconds. See the screenshot:
