Dear Molpro users:
I am trying to run first RASSCF, and then NEVPT2 using RASSCF state-specific natural orbitals. However, the NEVPT2 part fails with the following error:
***********************************************************
**STARTING THE PERTURBATIVE CALCULATION**
Maximum of off-diagonal core Fock matrix is: 0.1143724829D-05
? Error
? Closed-shell block of Fock matrix not diagonal. Please use state specifc orbitals
? The problem occurs in Readfm
GLOBAL ERROR fehler on processor 0
***********************************************************
I am also attaching my input and output. Can anyone kindly help me get rid of the error?
thanks in advance, and regards,
Gaurab
