hello amber user.,
 
        Equilibration stopped in between, while heating the system
(DNA+Na+ions+water), from 0 k to 300 k.(increment of 15 k in each steps).
it was stopped in the 210 k to 225 k step.........
  
i got the following message in my output file...........
  
 " EWALD BOMB in subroutine ewald_list
   volume of ucell too big, too many subcells
   list grid memory needs to be reallocated, restart sander"

can anyone tell me what does it mean?
thanks in advance
regards
fredrick.
