casscf-tete

Casse-tête (n.m.): Au Québec, un puzzle. --- Larousse dictionary

casscf-tete is a simple program that builds input decks for US-GAMESS CAS-SCF calculations.

Usage

Call it with the number of electrons of the molecule and your choice of HOMO and LUMO orbitals, and it will print out the appropriate $guess and $det decks,

$ ./casscf-tete 60 --homo 24 28 29 30 --lumo 31 37 34 33 --norb 270
 $guess guess=moread norb=270 norder=1 $end
 $guess iorder(24)=27 iorder(27)=24 iorder(32)=37 iorder(37)=32 $end
 $det ncore=26 nact=8 nels=8 $end
