Hello, I am a new user of QChem and I would like to run stand-alone QM/MM calculations for a large zeolite model containing various metal complexes in the pore space.
I have a few questions,
I am having to define atom types, charges and LJ parameters for my system. If I define only these three parameters, does QChem use the forcefield defined in the $rem section to fill in the other parameters such as bond, and torsion parameters?
What are some tips to speed up the QM/MM calculation?
