Dear Zac Smith,
this is to say that your SCF does not converge. The usual measures to sustain better convergence
have been previously described in this forum, so may locate them by browsing/searching the forum.
Surely, ALPHA 0.4 is definitely way too large, so start by setting it to 0.1 or even lower …
Best,
Thomas Kühne
