Hello,
I modelled a bullet as a rigid element and requested its velocity from the history output. Even though the simulation went good, why did I have such a rough graph?
Thank you so much!
I assume that it’s explicit dynamics analysis. Such noise is normal, it’s called aliasing. Acceleration and (reaction) force output is particularly susceptible to that. But you can just use filtering to get rid of this. Go to Create XY Data —> Operate on XY data and choose a filter from the list of operators. Specify the parameters and plot the results.
