czhao86 is on a distinguished road

I have a setup to study the focusing of nanoparticles by a optical force field, and the particle particle interaction is critical. However, once I add the DEM collision, the particles are staying in their positions, and in the iteration process, there is only one curve about energy. Anyone have some ideas?
