Hi all,
I am trying to optimize the excited state of a cluster, but the optimization fails in job.13, after the dscf and escf converge, with this error message:
----------------------------------------
S+T+V CONTRIBUTIONS TO ENERGY GRADIENT
----------------------------------------
1e-integral 1st. derivatives will be neglected if expon. factor < 0.100000E-10
gradient run cancelled due to user signal in (i|STV|j)` : 2 1 0 0 (nshell= 259) !
MODTRACE: no modules on stack
*** this job must be restarted ! ***
egrad ended abnormally
error in gradient step (1)
(END)
I am right now restarting the optimization with the new coordinates, but I would like to understand why this error occurred. Can anybody help me?
Thanks
Enrico
