Dear Amber Users,
i have did MD simulation for organic molecules using
Amber7. the following input i hvae used for the MD simulation.
MD_simulation of 64_PIMB
&cntrl
imin = 0, irest = 0, ntx = 1,
ntt = 1, temp0 = 454.0, tautp = 1.0,
ntp = 2, pres0 = 1.0, taup = 0.2,
ntb = 2, ntc = 1, ntf = 1,
nstlim = 300000,
tempi = 454.0, dt = .001,
cut = 10.0,
ntpr = 200, ntwx = 200,
&end
the results of the MD run as follows
NSTEP = 300000 TIME(PS) = 360.000 TEMP(K) = 458.62 PRESS = 84.5
Etot = 9125.9326 EKtot = 8922.7843 EPtot = 203.1483
BOND = 3155.1958 ANGLE = 3954.8001 DIHED = 2722.0354
1-4 NB = 2241.2389 1-4 EEL = -9234.5666 VDWAALS = -3937.0160
EELEC = 1301.4608 EHBOND = 0.0000 RESTRAINT = 0.0000
EKCMT = 84.3661 VIRIAL = -51.7373 VOLUME = 74581.5314
Density = 1.0329
Ewald error estimate: 0.1451E-03
i have doubt on the value of the pressure. i have given 1 atm as a
reference pressure in the input but in the final results the value is
about 85 atm or so..is it correct..
thanks in advance...anand
