Dear All,

I was wondering if there is a way to ramp (gradually change) a force constant during a simulation? For example, I introduce some distance restraints in my simulation, and I would like the force constant to be very small initially (to prevent the calculation from crashing), and slowly increase the force constant during the simulation - is there an easy way of doing so?

The only way I found to do this is to run a series of simulations - simply changing the disre_fc parameter in each step.

Cheers
Flemming
