IRC_MAXSTEP
IRC_MAXSTEP = real
Default: IRC_MAXSTEP = 3.000
Description: Upper limit for the step size (in fs).
The damped-velocity-Verlet algorithm for the IRC calculations uses an adaptively varying size of the time step. It depends on the estimated accuracy of the previous step. IRC_MAXSTEP defines the upper limit for the step size in fs.
