I just came across this fantastic capability of Gromacs, user-specified
potential functions, which can let me use LJ potential for some atom pairs
whereas Buckingham for some others. However, I have a doubt about topology
file construction, even after reading a document by Gareth and going
through earlier posts on this mail-list. I would be highly obliged if
anyone can help:
Specifically, since I have LJ and buckingham both, do need to repeat
statement mentioning nbfunc ( and combination-rule) in .top file? e.g.
nbfunc=1 followed by LJ parameters C and A for the concerned pairs and
then nbfunc=2 (and whatever combination rule) , followed by buckingham
parameters C, A , B for concerned pairs in the .top file?
Thanks a lot!
