TDDFT with M06 requires second derivatives that have not been coded yet. We're working on making those available.

hello again,

i'm trying to run a tddft calculation on nwchem 6.0, 16 processors, and i'm getting the following error message:


 Entering Davidson iterations

 Iter   NTrls   NConv    DeltaV     DeltaE      Time

which is kind've confusing... here's the input file, left out the geometry, it's just long and cumbersome:

echo

start molecule

title "1"
charge 0

geometry units angstroms print xyz autosym noautoz
  • coordinates here*
end

basis spherical
 * library 6-31G**
end

dft
xc m06-2x
direct
iterations 500
end

tddft
nroots 10
end

task tddft energy

thank you for your help!
