These values are completely dependent on the simulation that you are running. I will explain what step size is in a quick example. Say you have a range from 0-100 seconds and you would like to sample values across this range of time. If you consider your step size in regards to your sampling time:
- A step size of 10 would take a value every 10 seconds and give you 10 data points to use.
- A step size of 1 would take a value every 1 second and give you 100 data points to use.
A high step size will run quickly but take few data points and conversely a low step size will take many data points but take longer to run as a result.
So as i said before, it depends upon the application.
- If you would like to note precise changes, then it is recommended to use a smaller step size.
- If you are not concerned with precise changes and would like to run faster, then use a larger step size.
