Hello everybody,
I need to extend Ryckaert-Bellemans parameters to C6 in order to take
into account dihedrals in alkyl chains. What parts of the source code
need to be modified exactly? I'm sure it is pretty trivial to do that,
but I can't find by myself the functions and/or structures involved in
the R-B potential calculation. Can someone help me? I have already a
.itp file with the correct number of parameters.
Nicolas
ps: I have read the previous posts on the topic... Unfortunately, the
parts of the code to modify were not indicated.
You can actually do it simpler. By adding a proper dihedral with
multiplicity 6 in the top file. You then have two dihedral functions on
one bond.
