Dear all, <div><br></div><div>I want to use Lagrangian MTD to study a reaction (since the barrier appears to be high), I checked the CP2K manuals and the example at <a href="https://www.cp2k.org/exercises:2015_cecam_tutorial:mtd1">exercises:2015_cecam_tutorial:mtd1 [CP2K Open Source Molecular Dynamics ]</a></div><div>I found that I need to specify 4 parameters for Lagrangian MTD, </div><div>(1)TEMPERATURE</div><div>(2)TEMP_TOL </div><div>and for each CV, </div><div>(3) LAMBDA</div><div>(4) MASS</div><div><br></div><div>my questions are </div><div>(1) I understand why TEMPERATURE need to be specified, but why TEMP_TOL (temperature tolerance) has to be specified?</div><div>(2) is LAMBDA the force constant for the fictitious particle? what's the unit?</div><div>(3) what would be good values for TEMP_TOL and (most importantly) LAMBDA, and, how to tune LAMBDA? </div><div><br></div><div>Thanks,</div><div><br></div><div>Alh.</div><div><br></div><div><br></div><div><br></div>
