You see, I have a system with Si, O, H, and water, H, O.
They are atomic types 1, 2, 3, 4, 5.
I have a force field that I’ve already tested and works very well for water (4, 5), but it doesn’t describe the interaction with Si. I would like the substrate (1, 2, 3) to be using one force field, and the interaction between 4 - 4, 4 - 5, and 5 - 5 to be handled by another force field. The interaction between water and the substrate could be handled by the substrate’s force field.
Thank you.
