[molpro-user] Problem with CC norm

[Stavros Kardahakis]

Dear MOLPRO users,

I have some problems with CCSD(T) calculations, both RCCSD(T) and
UCCSD(T). In particular, many times I get the error message:
"Unreasonable norm. Calculation stopped" and then the job crashes. Is
there any way someone can bypass this bottleneck (perhaps ask for
another type of normalization) of the CC routine?

Sincerely yours,
