What does DT means in the "Fixed-step size (fundamental sample time)" of the Simulink?

What does the "DT" means? I found the sampling time is 0.0125s.But I don't know where it is set. Is the sample time related to the "DT"? Thank you so much!

Hi Yanhua,

There is nothing inbuilt as per documentation as the Fixed step size is DT. One possibility is that there is a custom variable named DT with value 0.0125 in Base workspace or the model workspace. In that case the field would pick up the variable form the workspace.
