It is really a long time since my last post about research stuff, emmh?
This pix is generated using the shear-strain coloring in atomeye, and it shows the cross section of a Ni3Al column in compression test. From it you can easily tell that the most highly stressed area is actully the surface.

A PyMol generated gif file
This is the gif file showing how dislocation would grow in a
twenty-Angstrom radius Ni3Al sample when compressed. It is quite
impressive, beautifully shows how dislocations and slip planes grow and
interact with each other.
I have tried to use Protein Explorer before turning to PyMol. PE, as I
think, is too much tricky to manipulate and very picky on browser as
well. But all the things in PyMol are easy, you simply click some thing,
almost everything can be done! I do not know why there is even less
document on PyMol on the net than rasmol and PE. Perhaps that is due to
PyMol is a young software, hmmm?
Python rocks, sourceforge rocks!

Coordinate number method
This is picture is plotted completely at the same step as last one. This
time I use the coordinate number method to plot it. It is beautiful as I
have imagined.

What the hell is it? Some kind of visual maze?
My supervisor ask me to plot out the morphology of the dislocation in
the compression simulation of Ni3Al. I got this when trying that using
relative displacement method. It shows the cross section area, and looks
like a maze, isn’t it? Perhaps I should also try potential energy and
coordinate number, which might give me different image. Hmmm…
I think I am much nearer to the key.
