Example: Subsystem TDDFT, coupled FDE excitation energies

Download SUBEXCI_dimer.run

#! /bin/sh

# This is example for coupled FDE calculation of excitation energies. The
# subsystem TDDFT code couples the monomer excitations to obtain the excited
# states of the total system (often denoted as coupled frozen density embedding,
# FDEc).

# First the isolated fragments are calculated, the TAPe21's of these fragments
# are t21.iso.rho1 and t21.iso.rho2. Next uncoupled FDE excitation energies are
# calculated in which one fragment is frozen and the other active. The key ALLOW
# PARTIALSUPERFRAGS is necessary to be able to use subsystem information for
# only one subsystem from a TAPE21 file of a previous FDE calculation.
