I have performed a series of some long simulations for a large system containing some molecules for which the Gromos54a7 force fields have been used.
Now in the next step of my research project I want to study the behavior of the system gotten from the first step on top of the Silicon surface. Unfortunately I could not find any Gromos54a7 force fields for Silicon surface but Charmm FF is available for it.
Considering the fact that mixing systems with different force fields doesn’t make sense, what would you recommend to do so that I would not loose the results (resource) gotten (spent) from (for) the first step?
