[gmx-users] How to use tabulated potentials to do coarse grained simulation?("Segmentation fault" when running mdrun.)

[Catfish SUN]

Dear Berk and all GMX users,

Thanks a lot for your instructions. I have corrected my errors and are
using h, h'' for my foces.
C12 is set to 1 correspondingly.
However I still get "Segmentation fault" when running mdrun.
the version of GMX that I am using is 3.3 and I also tried 3.3.3
Are there still anything wrong with my setting files?
Need I specify energy groups in mdp file?

Thanks a lot
