Constraint methodThis method is similar to velocity rescaling as seenthrough a Taylor expansion of : 1 TT 12tT2tTt T 1 1t T for small Δt and small (T – T ), giving:TT121Constraint methodFinally, another alternative would be todetermine the friction coefficient ξ through: mk TTQwhere m is the number of degrees of freedom(m = 3N -3) andQ the „thermal inertia“,a fit parameter describing the relaxation.But the time scale is artificially dominated by Q.122
