I'm trying to start a dynnamic calculation from a minimization restart
file using PME but the dynamic doesn't start and the .info file appears
like that:
NSTEP =     0  TIME(PS) =    0.000  TEMP(K) =    49.83  PRESS =     
0.00
 Etot   = nan           EKtot   =    3717.9879  EPtot      = nan
 BOND   =    7283.3858  ANGLE   =    2961.6355  DIHED      =   
1531.1235
 1-4 NB =    1093.7476  1-4 EEL =   12371.7763  VDWAALS    =  
26778.8005
 EELEC  = nan           EHBOND  =       0.0000  CONSTRAINT =      
0.0000
 T_SOLUTE =    49.1895  T_SOLVENT =    49.9763
 Ewald error estimate: nan
My input is:
#Sander input for Dymamic
#
 &cntrl
 imin=0,nmrmax=0,
 ntx=1,irest=0,
 ntpr=100,ntwx=100,ntwv=0,ntwe=100,ntwxm=0,
 ntf=1,ntb=1,ntp=0,idiel=1,dielc=1.0,cut=10.0,

 temp0=298.0,tempi=50.0,
 ig=71277,ntt=5,tautp=0.2,tauts=0.2,
 iewald=1,
 &end

80 80 72       3 0 0 0
0.00001
END
END
And the sad end of the sandout is:
 bombs away
 bombs away
 bombs away
 bombs away
 bombs away
 bombs away
 bombs away
 bombs away
 bombs away
 BIG PROBLEM in grid_ucell!!!
 
Can you please help me?
