Hi,

Is there any software for creating crystal structure in 3D (e.g. to visualise the FCC, BCC, HCP structure)? In addition, I would like to apply simple strain on such structure and observe the changes?

I don't do crystals but I hope to apply these knowledge in the interaction of particles/droplets/bubles when they are closely packed.

Assistance appreciated

Cheers

Pymol makes pretty pictures from crystal data. I've worked with Refmac and Coot for more serious crystal manipulation, and they seem to do just the job :)

drawXTL (http://home.att.net/~larry.finger/drawxtl/) ist the program you are probably looking for.
If you just want to look at hcp, ccp and bcc packaging types you might as well look here (http://ruby.chemie.uni-freiburg.de/Vorlesung/Strukturtypen/alle.html). There are a lot of other structures as well. This site is in german but AB2 or "Perowskit" are pretty self-explanatory.
To view a 3D model you will need a VRML viewer such as vrweb which can be found in the ubuntu repositories, but I don't know the section right now (maybe universe). The program is rather antique but it will do its job well enough.
