Dear GMXuserr,
To use LJ (6-9) in my simulation, I followed the manual as below:
In .top file:
nbfunc comb-rule
1 1
In .mdp file:
coulombtype = user
vdWtype = user
Also, I provided a table.xvg for LJ(6-9) in my working directory.
Normally invoked the "gmx grompp -f mini.mdp -c case.gro -p topol.top -o
mini.tpr"
But it ends with a fatal error stating that cut-off and PME ... , must be
used for coulombtype and vdWtype.
Would you please let me know where I am doing mistakenly or missing to do
so?
Cheers,
Alex
