Dear Experts/cp2k users ,
I am trying to simulate hydartion reaction at the liquid interface using
AdBF-QMMM. When I add keywords of adbf at Force-MIXING SECTION, the error
occurs (Force-mixing failed to find QM_KIND mapping for atom of type O)
.For QM_KIND_ELEMENT_MAPPING keyword, the official website gives the
following explanation: *Mapping from elements to QM_KINDs for adaptively
included atoms.* I don't understand what this means. Is it the type of
atom corresponding to the atoms (C, H, O, etc.) in QM region? In the pdb
file, I use OT to represent the O atom. Is the keyword set like this :
QM_KIND_ELEMENT_MAPPING OT O? In addition, is QM_KIND set to O or OT?
On the other hand, do the & QM_ NON_ ADAPTIVE and & BUFFER_ NON_ ADAPTIVE
Section need to be set? When MM_INDEX keyword in QM_MMBUFFER_ NON_
ADAPTIVE is set, does this mean that the atoms can only be in the buffer
region?
Thank you for any possible help.
