Droplet trajectory and track file
 

Hello

I have gotten a simulation case and data about an injection into a pipe.
I wish to see the droplet trajectory, so am following the different steps on how to plot them from the user and tutorial manual, using the particle tracks menu.

However, when plotting the results, I am getting the droplets at their last position (the last time step). Moreover, the 'pulse' switch is not available.
Does anyone know why I am getting only the lat time step? do I have to setup something else that I forgot?

Thanks a lot for any help
