Dear Community,
I am trying to run a TD-DFT property calculation (optical rotation tensor, but I imagine the problem is relevant for any property). In particular, the SCF input to the CPHF module is obtained from a PBE+X2C calculation, e.g., the input is
'''
dft
xc xpbe96 1.0 cpbe96 1.0
end
relativistic
x2c on
end
property
response 1 0.0000
velocity
orbeta
giao
bdtensor
analysis
convergence 1e-4
end
'''
The same calculation seems to work without the x2c correction. This, together with the text of the error message, leads me to believe that the Hamiltonian in the CPHF module is not exactly the same as in the SCF calculation - is this assessment correct? If yes, is there a way to run this PBE+X2C calculation - or, an even more important application, is the XC kernel itself inherited in the property calculation, or is it actually ''just'' a CPHF run for the properties? This seems a bit unclear to me from the manual and the output file.
Thank you in advance,
