This e-mail address is for Chimera questions... we are not experts in other programs.
For Gromacs, see its own documentation, help archive, etc.
I can only say that molecular dynamics (MD) means that the atoms are moving, so they have velocities. There are several methods for assigning and adjusting the velocities in MD.
In the Gromacs MD documentation try searching for "velocity generation" and "velocity" to see all those parameters.
