Generating velocities is the only way to get new ones to start independent
trajectories. Otherwise, you'd have to somehow manually hack your .trr file to
write new velocities manually. If your objective is to start 20 independent
trajectories, then "gen_vel = yes" in conjunction with not using your .trr file
sounds like the way to go.

Why don't use different random (gen_vel =yes; gen_seed =-1 in .mdp
file) seed to generate the velocity?
