Numerical gradient failing after RASSCF/CASPT2
Hello,
I have ran the following input file:
&GATEWAY
coord= /something.xyz
basis=ANO-RCC-VQZP
group=nosym
&SEWARD
&SCF
iterations=40
&RASSCF
spin = 5
charge=0
nactel=4
inactive= 36
RAS2= 4
symmetry=1
ALTER
1
1 36 38
ITER= 80,25
CIMX= 25
&CASPT2
prop
maxiter=30
&MCKINLEY
perturbation
hessianI ran everything successfully up to CASPT2 in a separate file. When I add McKinley, it fails:

Parameters for step-restricted optimization
Maximum step length (initial seed): 3.00E-01
-RFO activated with parameters:
Maximum number of data points used in RFO: 5
Line search is performed
-Optimization for transition state.
Optimization method: RS-P-RFO
No mode to follow is specified!
Optimization will follow mode with the lowest eigenvalue.
-Initial Hessian guess is estimated with finite differences.
Two point symmetric formula, Delta= 1.00E-02
-Hessian update method: Broyden-Fletcher-Goldfarb-Shanno
Maximum number of points in Hessian update: 5
-Relaxation will be done on non-redundant internal coordinates, based on
force constant weighted redundant internal coordinates.

Re: Numerical gradient failing after RASSCF/CASPT2
You probably need to have two RASSCF inputs: one to prepare the orbitals and a "clean" one, without ALTER:
&RASSCF
spin = 5
charge=0
nactel=4
inactive= 36
RAS2= 4
symmetry=1
ALTER
1
1 36 38
ITER= 80,25
CIMX= 25
&RASSCF
spin = 5
charge=0
nactel=4
inactive= 36
RAS2= 4
symmetry=1
ITER= 80,25
CIMX= 25Offline
