feram is a fast molecular dynamics (MD) simulator for bulk and thin-film ferroelectrics and relaxors.


This program, compasses, searches maximum, minimum and saddle-point states of finite size dipole arrays (i.e. sets of compasses).


This program, loto, analyzes dipole-dipole interactions in the systems with periodic boundary conditions. 3-dimensional bulks, 2-dimensional films and 1-dimensional wires can be treated. loto can plot dispersion diagrams of optical phonons for the dipolar systems


xtalgrowth is an X application which simulate crystal growth of 2-dimensional hard spheres. If you execute xtalgrowth, a window opens, hard spheres fall from random positions, and they stacks at the bottom of the window.

feram, compasses and loto are written in Fortran. xtalgrowth is written in C with X11 libraries.


ulmul is a ultra light-weight markup language for generating HTML files.
