Dear Dr. Iurii Timrov,
Thanks for the reply.
I was trying in different way to converge scf calculation in case of carbon
dimer without "smearing". First I converge the system using "smearing" then
again I performed the scf calculation by changing the "restart_mode" from
"from_scratch" to "restart". In this condition, the scf calculation for
carbon dimer is converging & also turbo_davidson.x is possible. Do you
think, this is a right approach ??
Also I have observed that if I am using hybrid functional, the system is
converging normally (keeping the restart_mode = from_scratch & without
"smearing").
Can I compute the absorption spectra for a molecule having triplet ground
state using turbo_davidson.x or turbo_lanczos.x ??
Thanks & regards,
