Hi all,

I am wondering is there a tool or an accepted method to convert the velocities from a all atom simulation to their corresponding coarse-grained bead velocities. I am trying to use short scale atomistic sims to inform the initial trajectory of longer scale coarse-grained runs.

Thanks

I'd just sum (I.e. take the resulting vector of) all the velocity vectors of the atoms that map onto that bead.
