hi everyone...

i just wanna ask, is it possible to get data accuracy more precise than the time step. for example, in some simulation we set the step to be 1 second but in the sample time we want to get the data accuracy every 0.01 second, so it means 100 data during the 1 second step. can we???

thank you

best regards

No, the best you would be able to do would be to interpolate the values at the intermediate times, which is not going to be any more accurate than the way-points, and is going to be less accurate unless the interpolation function matches the underlying equations.

If you need accuracy to 0.01 then use that as your time-step.
