[DFTB-Plus-User] the code does not work when nxvv > nxov

[Benjamin Hourahine]

Hello,

the version of the TD code I have access to has commented out this test, as this is only an issue for cases where the state of interest is above the maximum number of empty states included in the Casida equations. I would suggest editing that test out also (but I don't know the history of the source code you have, since this is not yet part of an official release).

Regards

Ben

Dear　all,

　　When I use TD-DFTB method　doｉｎｇ Excited－state structure optimization. This error happens:sorry, the code does not work when nxvv > nxov.　Could someone please tell me the reason? Thanks　very　much.　Following is my control　file:

Geometry=GenFormat{
  <<<"in.gen"
}

  MaxSteps = 2000

  # LatticeOpt = No
  # FixAngles = Yes
  # FixLengths = {Yes Yes No}
  # Pressure [Pa] =  1E+6
  }

Hamiltonian = DFTB {
  SCC = Yes
  SCCTolerance = 1.0e-7
  MaxSCCIterations = 1000

  }
  Dispersion = LennardJones {
  Parameters = UFFParameters {}
  }

  }

   #   LowerCaseTypeName = Yes
  }
  LinearResponse = {
  NrOfExcitations = 100  # Gives the number of the solving states
