Dear CP2K developers,<br><br>I have some doubts about my QMMM calculations (I'm simulating one quantum glucose molecule <br>in a classical Ionic liquid + water solvent).<br><br>I
set &PERODIC = NONE for QM CELL, in &QMMM (and I set no PBC in DFT section
for the POISSON solver),
&PERIODIC = XYZ in &SUBSYS and I set<br>ECOUPL=GAUSS for the QM/MM interaction.<br><br>I have several question about the PBC:<br><br>1- with this setting I'm decoupling the QM CELL from all the other
periodic QM images (because I set &PERODIC = NONE for QM CELL ), keeping only the zero-cell electrostatic between QM
and MM + <br>the interaction between QM and MM repeated images up to the cutoff (because I set &PERIODIC = XYZ in &SUBSYS )?<br><br>2- with this setting MM atoms interact only with the thier images or also with the QM images (because I set &PERIODIC = XYZ in &SUBSYS )?<br><br>3- if I set &PERODIC = NONE for QM CELL and PERIODIC = XYZ in DFT section for the POISSON solver, would it has sense?<br><br>4- if QM CELL hasn't PBC (as in this case) there is the possibility that the QM atoms go away from the QM box?<br><br><div>Can someone clarify this to me?<br></div><div><br></div><div>Thank you very much </div>
<div>Kind Regards</div><br>Marco<br>
