[molpro-user] MULTI RESTART

[David Ambrosek]

Hello again,

You are right, it would be easier to just set START as follows:

start,2140.2

for example. This was also tried but doesnt work if you send in your 
second job. You see I have no problem using start if it is within the same 
job. But the moment my job ends and I need/want to start from specific 
orbitals then it just doesnt seem to work. So I want to verify that you 
use START even for resent jobs?


I am just wanting to get my gs wavefunction for my system. If the orbitals 
are good, then I want to increase to more states. After I have these 
states then I would like to run caspt2 on them etc. So it is always 
building on the step before, but if I can not save these orbitals properly 
and then 
recall them properly, then it is just a lot of wasted time!

Can you expand on this topic,
thanks again,
