WebThe rigid and rigid/small and rigid/nve styles perform constant NVE time integration. The only difference is that the rigid and rigid/small styles use an integration technique based on Richardson iterations. The rigid/nve style uses the methods described in the paper by Miller, which are thought to provide better energy conservation than an iterative approach.
