1) The first step is to create a molpro input deck that controls how the CASSCF electronic structure calculations are performed. AIMS requires a fairly complicated structure to the molpro deck and it is highly recommended that you use the ethylene CASSCF example as a starting point (section [[ab initio multiple spawning dynamics# | 1) The first step is to create a molpro input deck that controls how the CASSCF electronic structure calculations are performed.

3) The AIMS calculation is then initiated by running molpro on the input deck, in the usual fashion. In order to sample different initial conditions, multiple AIMS simulations should be run with different values of the random number seed '' | 3) The AIMS calculation is then initiated by running molpro on the input deck, in the usual fashion.
