Yes, you can study a non-conventional lattice in kwant too. Please check the answer by Anton  on this topic and my comments on a similar program shared by a kwant-user (the study of transport in DNA.)
If you have an interesting problem or code that you may want to share on this topic for the kwant community that would be wonderful!
I hope this helps, Adel

thank you in advance.
I have some questions:
How can I Kwant for 3D surfaces studies?
I have done a code that gives me the coordinates for a discretized surface, for example a real nanotube.
So, how can I use these coordinates to make my Kwant system?
In the manuals there are just examples for "cubic" 3d system but what I hope is to analyze 2D structures embedded in the R3.
