About"ga orthog: hard zero"


Just Got Here
Hello,every one. I tried to perform SODFT calculations with a specific molecule, but the procedure broke down with the error of "ga_orthog: hard zero". Peculiarly, the conventional DFT calculations with this molecule or SODFT calculations with the analogues are all normally terminated.

here's the input of this pathological task:

Is this error associated with the input geometry of this molecule ? Or the bugs of the procedure?

Linear dependencies
Unfortunately, the spin-orbit code does not correctly handle the linear dependencies associated with your case.

The work-around is to add the line set lindep:n_dep 0 just before the task line, i.e.


set lindep:n_dep 0

task sodft
