dear gromacs users
I tried to add ions to my .gro file as it was showing the warning that:-
System has non zero charge.
But a new error occured when i run grompp command again:-

Source code file: /build/buildd/gromacs-4.6.3/src/kernel/toppush.c, line:
1412

Fatal error:
moleculetype CU1 is redefined
