I am trying to do a calculation on an artificial line charge in vacuum. The
line charge has 267 atoms and each atom has a 1e charge. The atoms are
bonded by a bond term and an angle term. I defined the required itp files
and top file. When i issue
grompp_jpt -v -c parallel.gro -p chain.top -f nve.mdp
I get the following error message.
Program grompp_jpt, VERSION 4.5.3
Source code file: grompp.c, line: 175
The largest charge group contains 267 atoms. The maximum is 32.
For more information and tips for troubleshooting, please check the GROMACS

What should i try to do to circumvent this error.
