Fast Fourier Transform based Homogenization

FFT based Homogenization for heterogeneous materials dealing with electric or heat conductivity.

Implementation of Fast Fourier Transform based Homogenization for heterogeneous materials dealing with electric or heat conductiviy. It takes the values of conductivity at regular grid of periodic unit cell that represents the material and produces the distribution of local fields such as electric field and electric current or temperature gradient or heat flux. The effective conductivity matrix is also produced. The algorithm works both in two and three-dimensional case.
