Dear Tahere, 

your geometry optimization is far from being converged. Instead of limiting the number 
of optimization steps to 30, better simply rely on the convergence criteria. 
SCF convergence, however, is much better when OT switches into the SD fallback mode 
is always bad news. Try to reduce the OT stepsize …
