Research data supporting the paper ""Gradient elasticity in Swift-Hohenberg and phase-field crystal models"". Python Notebooks Notebooks (extensions .ipynb) work "as is" with the dataset from folder TRI1_100 Code (apfc-fft.zip) The implementation of the APFC model is performed in python by exploiting the pseudo-spectral Fourier method. Library pyfftw is adopted. However, standard fft libraries can be used as well by changing the corresponding module/functions. GitLab repository https://gitlab.com/3ms-group/apfc-fft-ge
