<div>Dear Colleagues,</div><div><br /></div><div> We have an issue with the usage of the option "REFTRAJ": It seems that the forces are zero even if the option "EVAL_ENERGY_FORCES" set to "TRUE". Otherwise the data, like the rewritten trajectory in the format .xyz, the "MOMENTS", ...<br /></div><div><br /></div><div> My section on the dynamics:<br /></div><div><br /></div><div> &MD<br /> ENSEMBLE REFTRAJ<br /> &REFTRAJ<br /> EVAL_ENERGY_FORCES T<br /> TRAJ_FILE_NAME traj.xyz<br /> &END REFTRAJ</div><div> ...</div><div> &END MD</div><div><br /></div><div>The option "EVAL_ENERGY_FORCES" is found in the resulting file .restart, so it has been correctly read and interpreted:</div><div><br /></div><div>...<br /></div><div> EVAL_ENERGY_FORCES T<br /></div><div>...<br /></div><div><br /></div><div> I have also the section '&FORCE_EVAL / &PRINT / &FORCES' defined,</div><div><br /></div><div> &FORCES ON<br /> FILENAME =${SYSTEM}-1.forces<br /> &EACH<br /> MD 1<br /> &END EACH<br /> &END FORCES</div><div><br /></div><div>but the output file remains empty, even if this option works within normal MD runs (without 'REFTRAJ').</div><div><br /></div><div> I would be thankful for any kind of hints on what I am doing wrong. :(<br /></div><div><br /></div><div> Greetings from Paris,</div><div><br /></div><div> apsi<br /></div>
