|Other||Very fast calculation of dipole–dipole mutual interactions using fast Fourier transform (FFT). The software can calculate bulk materials as well as perform simulations of ferroelectric thin film condensers. Compilation and development under different environments is made easy thanks to GNU Autotools. Developer's comments on feram (Japanese) Dipolar moments and ferroelectrics (Japanese)|
