<DIV><FONT face=Arial size=2>I want to analyze the energy during a normal
simulation. Some strange things happened.</FONT></DIV>
<DIV><FONT face=Arial size=2>In mdp file, I selected DNA, NA+, SOL for energy
groups output. When I analyzed edr file by g_energy, I found Coul_LR is always
ZERO. I think my parameters have no problem, rlist = 1.0
rcoulomb = 1.0, rvdw = 1.0. Furthermore, when I selected
'System' for energy output, Coul_LR have some reasonable values.</FONT></DIV>

<DIV><FONT face=Arial size=2>When I do MD simulation in other computer,
there is NO output for Coul-LR with the SAME parameter
file. </DIV>
