Hi,

I have a couple of hundreds of particles, initially randomly distributed with random particle size. These particles, then start to move under magnetic field.

I would like to plot the particles as function of time (prefer also with particle size shown).

Is there any open source (or free binary) software that can do this? and Also what input format is needed and how to do it in that software. I know that paraview can do this, but, does not know the format required and how to do it in paraview.

Thanks!
