651. N/EDA in GAMESS. 3. Running L/CMOEDA

As it turns out, while MOEDA works fine with pure and hybrid functionals, it does not appear to like PCM, giving weird results.

Here's an example of a run that works, with a few key words highlighted:

The ! comments out the PCM lines. I generated the input from an .xyz file through avogadro, and then edited the file manually to get the charges etc. right.

Here's the output:

649. N/EDA in GAMESS. 1. Recompiling GAMESS US with NBO6

I need to do energy decomposition analysis (EDA), but only have licenses for Gaussian and NBO6 (i.e. not ADF, turbomole, QChem etc.). NEDA isn't supported by NBO6 with gaussian (afaik).

NWChem, my usual gaussian alternative, doesn't support NBO6 beyond writing a .47 file.

Enter GAMESS US. I've been trying out gamess every few years, but I've found that it's slow and unreliable (very difficult to get SCF convergence) for the systems I work with (polyanions). Some of this may obviously be down to my lack of familiarity with the code -- there are probably plenty of satisified users of GAMESS US.

Either way, NBO6 suppports NEDA with GAMESS US. Also, GAMESS US does two different types  of   EDA: the common Morokuma-Kitaura (MOROKM) one (although only with HF) and an alternative approach by Su and Li that's referred to by GAMESS as LMOEDA (or CMOEDA).

MOROKM and LMOEDA as supported out of the box by GAMESS, but to get it to do NEDA you need to re-link it against NBO. Luckily it's even easier than the instructions in the NBO gamess file (i.e. no need to edit code).

NOTE: I could only link with gfortran 4.9 (jessie). gfortran 6.3 (stretch) failed to link (messages re -fPIC; recompiling gamess with -fPIC didn't solve it).

To compile gamess, see e.g. http://verahill.blogspot.com/2013/06/4xx-gamess-us-2013-r1-on-debian-wheezy.html

Once you've done the ddi/comp and compall steps, edit lked and search for NBO. Change to

set NBO=true
set NBOLIB="/opt/nbo6/bin/gmsnbo.i8.a"

assuming that this location is correct.

Then do lked as in the post above.
