Hi All

      I am trying to perform single point calculations with B3LYP-D3/LANL2DZ+631G* level of theory on B3LYP-optimized geometry on some of my transition metal complexes, but the convergence is not be achieved in certain cases. I am getting the following message:

dft energy failed

this type of error is most commonly associated with calculations not reaching convergence criteria.

Please suggest some ways to iron this issue out.

Thanks in advance
