Hi,
I'm trying to restart a TDDFT calculation in NWChem 6.1 as I believe that should be now possible. To do so I have modified my input file to:
restart min
basis
C library 6-31G**
H library 6-31G**
end
dft
xc xcamb88 1.00 lyp 0.81 vwn_5 0.19 hfexch 1.00
cam 0.33 cam_alpha 0.19 cam_beta 0.46
direct
iterations 100
end
TDDFT
CIS
NROOTS 6
NOTRIPLET
END
TASK TDDFT ENERGY
When I run this input file in the directory where there also the files from the previous run of the same TDDFT calculation that ran out of time then NWChem starts, proceeds to the TDDFT part of the code and starts the iterative procedure but then crashes with an error message:
Entering Davidson iterations
Restricted singlet excited states
Iter NTrls NConv DeltaV DeltaE Time
---- ------ ------ --------- --------- ---------
1 6 0 0.86E-01 0.10+100 1202.0

3 18 0 0.28E-01 0.84E-02 1202.1

For more information see the NWChem manual at
bgj_get_scf_dens movecs output =
./min.movecs
Now I have two questions:
1) What could cause this crash and is it in anyway related to me trying to do a restart?
and
2) If this is a restart and in the previous job it had already found 4 converged vectors why does it start again with 0 converged vectors and stays there until it crashes.
Any suggestions would be more than welcome.
Thanks in advance,
Martijn
