If you are looking for generating synthesized microstructures for using it in Phase-Field simulation, the best choice is Dream 3D, where you can control the distribution of grains and their crystallographic orientations: If you are looking for a framework to generate synthesized polycrystalline structures for molecular dynamics simulation, the best tool is ...

The $\Sigma$ values represent the volume of the Coincident Site Lattice (CSL) of the grain boundary in terms of the volume of the unit cell of the crystal. In general, grain boundaries with higher symmetry have lower $\Sigma$ values. Note that CSL boundaries are special grain boundaries. So, they do not represent all grain boundaries comprehensively. But, ...

Alone Programmer's answer already mentions ways to generate polycrystalline microstructure. To add to that, it is possible to generate models of bi-crystals to analyse particular grain boundaries directly using LAMMPS. Here is a detailed wiki on how to generate such models. Apart from this, there was a Java based applet called GBStudio that made generating ...

In 2008 I wrote a Python script to generate bicrystal models in a PBC box. Since the boundary is periodic (due to PBC), it's always a coincidence site lattice (CSL) boundary. The script is in repository named gosam and is documented here. The math was based on H. Grimmer's paper "The generating function for coincidence site lattices in the cubic system", ...

General Info As far as I understand you're taking a Fourier Transform of an image. In your case, that image corresponds to that of a microstructure alloy. So basically in 2D-Fourier transforms we are trying to model the intensity levels of the image and represent it in terms of a frequency plot. This is analogous to the 1D Fourier transform. Is there a ...
