Dear every cpmd user,
I am studying a mixture of water and aother solvant.
After 5ns using classical MD, I pick up a configuration as initial geometry to carry out the CPMD.
After optimization of wavefunctions, the molecular dynamic was carried out, my input file look like as follows,
&CPMD
MOLECULAR DYNAIMCS CP
RESTART WAVEFUNCTIONS COORDINATES LATEST
MAXSTEP
10000
TIMESTEP
5.0
EMASS
600
NOSE IONS
350.0 3000.0
&END
........
My system contains 624 atoms, the DFT is BLYP.
but the output file look like as follows,
TOTAL INTEGRATED ELECTRONIC DENSITY
IN G-SPACE = 1296.000000
IN R-SPACE = 1296.000000
(K+E1+L+N+X) TOTAL ENERGY = 1060.70424073 A.U.
(K) KINETIC ENERGY = 1152.16714712 A.U.
(E1=A-S+R) ELECTROSTATIC ENERGY = 623.45349978 A.U.
(S) ESELF = 1633.00373444 A.U.
(R) ESR = 104.08282525 A.U.
(L) LOCAL PSEUDOPOTENTIAL ENERGY = -246.43453910 A.U.
(N) N-L PSEUDOPOTENTIAL ENERGY = 71.85023843 A.U.
(X) EXCHANGE-CORRELATION ENERGY = -540.33210550 A.U.
GRADIENT CORRECTION ENERGY = -27.19522460 A.U.

Originally, I think the timestep is not correct, but when the timestep is increased to 10.0, the NaN ocurred, so I did not know the reasons,
can you help me?
