[DFTB-Plus-User] Removal of rotational and translational degrees of freedom in DFTB/MD

Hi All,

Does anyone have a version of DFTB+ where the 3 rotational and 3
translational degrees of freedom are removed during an MD run?  We are
performing nonequilibrium MD simulations and do not require to simulate a
canonical ensemble.  We also would prefer not to freeze certain atoms as we
feel this would be an even more severe interaction with the “real” dynamics
of the system.

Thank you, with best wishes
