CC optimization and structure retrieval

Aggelos,

If you do a

  grep "@" 

on the output file, do you get multiple lines? If not, your optimization has not done a step yet. After each step generally a geometry is printed, look for "Step X" X being a number in the output.

Remember, the CCSD/CCSD(T) geometry optimizations are done using numerical gradients. Depending on the number of atoms it will have to do a significant number of displacements to get the gradient and make a step.

[QUOTE=Aggelos.avramopoulos Sep 24th 9:30 am]Dear NWCHEM users,
i want to make some CCSD/CCSD(T) optimizations using NWCHEM.
Due to limit restrictions the comp. stopped. I have two questions:
A) How can i visualize the current structure. As far as i can see no
coordinates, except the initial ones, are given.
B) How to restart the process from the last successfull opt. geometry?
Thanks in advance for any help.
