Dear Gromacs experts,<br><br> I am planing to use tabulated potentials for dihedral functional form Summn over 'n' 0.5*K [ ( Cos n(phi-phi0)] , Here 1<= n <= 3 . I have three different K values (i.e K1,K2,K3 ) one for each 'n' value ( Here 'n' is multiplicity). I have generated table and given the table number in dihedrals directive of the ffbonded.itp file, According to my understanding one has to supply K ( force constant ) value in addition to table number in topology. In my case I have three different "K" values, which "k" value do I have to take, Can I take sum of all the three "k" values or can I take arbitrary value.<br>
Any help please.<br><br><br>Thank you in advance.<br><br><br>Regards,<br>Ramesh.<br>
