Dear
I am facing problem while running Production.
Ihe AMBER Version is 7.
The machine i am using is PC and working on LINUX Platform.
Prevously when i am running SANDER at 405.200 PS i am getting some abrupt
values so i change the cut off from 9.0 to 10.0. The simulation is
running properly at 405.000 PS. The values are as follows:
**********************************************************
At 405.00 PS
NSTEP =182500 TIME(PS) = 405.000 TEMP(K) =298.60 PRESS =

***********************************************************************************
By changing cut off the simulation is running properly at 559.800. But
after it the simulation stop suddenly by givimg such values:
OLD LIST LOGIC; ntnb = 1
EWALD BOMB in subroutine setup_grids
Resulting cutoff is too small for your lower limit

check COM velocity, temp: 0.000000 0.00(Removed)
Can you suggest what the problem is and how can i rectify it...
This step i had done repeatedly and encounter the same problem at this
step only.
It can be a kind help from your side.
