Re: how to define the numsteps in ABF or metadynamics simulation?

Hi,

There is no rule. Try running a short calculation first and seeing
what happens, how fast things move, then maybe you'll want to adjust
some parameters anyway. To estimate the total time, look at published
ABF calculations on similar systems.

Cheers,
Jerome
