Dear All,
I am trying to simulate water flow in CNT and just followed the website:
http://cs86.com/CNSE/SWNT.htm
I did the following:
1. ffgmx.n2t
**** must change this files name to ffencadv.n2t and add the following 2 lines:
C C 1 C ; CNT Carbon with one bond
C C 2 C C ; CNT double bonded Carbon
2. ffgmxbon.itp
add the following line to it:
#####################################
[ bondtypes ]
; i j func b0 kb
C C 1 0.14210 478900.
#####################################
[ angletypes ]
; i j k func th0 cth
C C C 1 120.000 397.480
#####################################
[ dihedraltypes ]
; i l func q0 cq
C C 1 0.000 167.360
#####################################
But when I ran:
x2top -f SWNT_6_6_144.pdb -o SWNT_6_6_144.top -r SWNT_6_6_144.rtp
Error message appeared:
Can not find forcefield for atom C-1 with 2 bonds
.....
Can not find forcefield for atom C-143 with 2 bonds
Can not find forcefield for atom C-144 with 2 bonds
-------------------------------------------------------
Program x2top, VERSION 3.3.3
Source code file: x2top.c, line: 206
Fatal error:
Could only find a forcefield type for 0 out of 144 atoms
-------------------------------------------------------
Could you please tell me what is the problem? This works on Gromacs 3.3.1
Thank you very much!
Jue
