Hi Tim,

Take a look at the following modifications:

Geometry = GenFormat {
 <<< "GrapheneInput.gen"
}
Driver = VelocityVerlet {
    MovedAtoms = Range { 1 -1 }
    Steps = 1000000
    TimeStep = 400.0e-15
    KeepStationary = No
    MDRestartFrequency=10
    Thermostat = NoseHoover{
    Temperature[Kelvin] = 1500
#  ReselectProbability = 0.5
#ReselectIndividually = Yes
#AdaptFillingTemp = Yes
    CouplingStrength=100 }
    OutputPrefix = "GrapheneInput.out"
}

Hamiltonian = DFTB {
  SCC = Yes
  SCCTolerance = 1.0e-5
  MaxSCCIterations = 1000
  Mixer = Broyden {
    MixingParameter = 0.2
  }
  SlaterKosterFiles = {
    C-C = "C-C.skf"
  }
  MaxAngularMomentum = {
    C = "p"
  }
  Charge = 0.0
  SpinPolarisation = {}
  Filling = Fermi {
    Temperature [Kelvin] = 100.0
  }
  KPointsAndWeights= {0 0 0 1 }
}



Options = {}

ParserOptions = {
  ParserVersion = 3
}

Hopefully that helps.

Best,

Nir

Hello :)



We are trying to run a molecular dynamics simulation on a large graphene sheet and are having trouble coding the input and were wondering if you could help.  I have included the .hsd file I am using below my signature, but the error we keep getting is “HSD parser error: File ‘dftb_in.hsd’, Line 34.”.  We keep moving and removing enter strikes and get ether that error or a “missing child” error depending on what we move where.  Please let me know if you know of anything we are missing.  One of the issues we fixed earlier is converting {} notation to ‘’ and I am not sure that isn’t causing part of the problem:



Thanks so much
