Kirk,<div>I don't want to use HF orbitals, HF does not converge in my case (which should be resolved separately). When I explicitly give record number on frozen card then I already should have the orbitals to be read in. How can I get orbitals in record 2100.2 (say) at displaced geometry?</div>
<div>I tested it by performing a MULTI step with closed card, followed by MULTI with frozen card, it works, but there is no point in doing that, is there another way? </div><div><br></div><div>Wanyi,</div><div>closed orbitals are optimized (if I remember correctly) meaning longer runtime, 100's of seconds vs few second for each MCSCF iteration. I was hoping to runs caspt2 geometry optimization where the displaced geometry used pervious orbitals.</div>

I am not sure if this is a good answer to your question. But why not<br>
using" closed" instead of "frozen" for the core orbitals?<br>
