Local CASSCF
|
||
|
|
||
|
The program executes a succession of steps
|
||
|
|
||
|
1. Orbital transformation
|
||
|
- 2 possibilities:
|
||
|
- motra/molcost
|
||
|
- ijkl
|
||
|
|
||
|
2. CASCI calculation
|
||
|
- casdet/casdi
|
||
|
|
||
|
3. Density matrix calculation
|
||
|
- 2 possibilities:
|
||
|
- casdet/casdi (diagonalization of CAS+S)
|
||
|
- costnevpt/rodyall (contracted perturbation)
|
||
|
|
||
|
4. Diagonalization of the Density Matrix --> natural Orbitals
|
||
|
locnats
|
||
|
|
||
|
--> iterate: goto 1.
