With ORCA working in parallel on 16 processors now, my QMMM is going fast. But, if I add in frequency calculations, the QMMM simulations slows down, predictably. I don't necessarily need the thermochemistry for every step any way. So, my thought is watch the trajectory, and any steps where there is something "interesting" happening, such as a covalent bond forming, save the frame before the bond formation as a PDB and the frame where the bond has formed as a PDB, and then run a frequency calculation on those frames/structures, I guess holding the MM region frozen, and that would give me thermochemistry data for the important parts of my QMMM. What are your thoughts on this?
