I was very happy to find such useful and usable program, and now I’m
trying to use it in the educational process in the department of
"Material science and metal physics" of the Ufa State Aviation
Technical University.
Till nowadays a proprietary (and warez) Chem3D was used, but now it’s
a good time to switch it to Avogadro.
Tasks being performed using molecular modeling not include any
scientific jobs - only educational, so the lightweight and easy-to-use
program would be greatly helpful. But now during migration, I’ve got
some issues.
How can I get help with this issues?
Should I create a page in the wiki, or use this mailng list, or any
other mailing list?
Of course, once work will be done, I can publish workbooks, and,
possibly, other working material. Existing workbooks are in Russian,
and based on Chem3D program, so they won’t be such useful to anybody.

A wiki is a pretty good idea. I am a teacher myself and also using Avogadro (german highschool). I guess I would contribute to that wiki as well.

Ok, then I should start workiing on it. I’ll use Avogadro wiki, if
noone against this idea.
Thank you, that’s useful link, but we are much more physics than
chemists, so large organic molecules mostly out of our scope.
“Killer-app” for us will be simplest simulation of metallic bond - I
haven’t seen such feature anywhere. We don’t need precise results, or
“alloy prediction”, but simplest simulation of metals (with electron
delocalization) etc. will be great.

No, in fact, I’ve wanted to start an “Education” section of the
Avogadro wiki for exactly this purpose.

Hmm. That would need some sort of additional extension. I know of
several simple quantum chemistry techniques I’m trying to add, but I
don’t know about band structure.
Do you know of a simple tight-binding quantum code? (Or simulation of
electron gas in a metal?) Certainly we have some support for crystals,
so it would be nice to have solid-state band simulation as well.
Suggestions and/or contributions in this direction would be most
welcome!

I don’t know if such code exists, but i’ll try to find out it.

Looks like GAMESS-US has some support for solid-state systems, at
least it has support for Density Functional Theory, but but I’ve
found another package: LAMMPS (http://lammps.sandia.gov/). It’s
GPL-licensed, and under active development. Now I try to build it, and
AFAIU it can be built as a library. Input files are pretty simple, put
I don’t know in which form output files are produced. There are many
promising examples on their homepage, like crack propagation or
tensile deformation of nanowires. Could you take a look on it and give
some decision, if it easy or not to implement support of this package?

Keep in mind there are many applications of DFT in chemistry – for
strictly molecular systems. AFAIK, GAMESS-US has no support for
periodic boundary conditions, so solid-state calculations are out of
the picture.

LAMMPS is a great program and I’d love to see support for it. I
haven’t used it much, but it’s pretty easy to write code to parse
output.
Actually, the UFF method in Avogadro can support lattice minimization
– we just don’t (yet) have the code to do calculations with periodic
boundary conditions.
There are also a number of “free for academic use” programs which work
on solid-state and metals too.
