To Do

• convergence problem large clusters are not converging (even with large boxes and next nearest neighbors)
• convergence require large box size ( > interaction radius ) and at next nearest neighbor cell force assembling

Considerations

convergence problem

the problem may be because active cells are those which are within any nearest neighbor box. If we include just particles which are really within interaction radius to some active particle, it may be better.

to do so we should make staticActiveParticles and activeParticleAdepts ( which are its neighbors ).
