Can an implicit integration algorithm use a time-step much larger than the characteristic time in Brownian dynamics?

To simulate a bead-spring chain using BD (inertia-less) and using an explicit integration algorithm such as the one proposed by Ermak and McCammon, the time-step should be smaller than the...

How to choose time step in Brownian dynamics simulation?

1. I simulated bead-spring chains (with bond length and bond angle oscillation) in water to verify the equipartition theorem. However, diffrent mean energy values are shown with different time...
