Grain boundary fundamental zone plot in MTeX

Hi all,

I would like to congratulate the developers of MTeX for such a nice and useful code!

I have a general question; I am using MTeX 5.5.2. Is it possible to construct grain boundary fundamental zones in MTeX. For example, for FCC crystals, the fundamental zone of a sigma3 CSL boundary would be represented by a steriographic triangle having {111}, {110} and {112} as its three vertices.  

What I want to do is to plot the variations of GB properties, like GB energy, for certain sigma boundaries. I believe that the best way to show the variation in GB properties with change in GB plane normal (for the same CSL boundary) is to show color contours of that property in the corresponding CSL fundamental zone plot.  Is it possible in MTeX.

Best Regards,

Ralf Hielscher

Hi Sagar,

yes this is possible. However, this is an outdated MTEX forum. Please post your question at

Thank you very much and a happy new year.

Hi Ralf,

Thank you very much for your prompt reply. I originally tried it on the new forum itself, but the forum isn't accepting the category "Ask anything". Perhaps it may be the browser issue or something else.
This is why I posted it here. I shall try again.

A very Happy New Year to you too! Stay healthy and safe!
