DIANNA (Diffraction Analysis of Nanopowders) is a free software developed to simulate atomic models of structures from an ensemble of nanoparticles and to calculate their whole X-ray powder diffraction patterns and the radial distribution function. The main objects of investigation are the particles whose coherent scattering domains do not exceed several nm. DIANNA is based on the ab initio method using the Debye scattering equation. This method makes it possible to obtain information on the atomic structure, shape and size of nanoparticles. It can be applied also to non-periodic materials or coherently ordered structures. ...

is a interactive molecular visualisation program designed especially designed for coarse-grained simulation of non-spherical particles. Ellipsoids (Gay-Berne), disks, and custom shaped uniaxial particle (e.g. pear-shaped particles) can be represented.

...Now it can be used only 1 bar and 1 piston, for future it will be changed. Video of textcase: http://www.youtube.com/watch?v=TLYVSWkhXBI Software is tested and runs stable with up two 5000 SPH particles. Known Problems: If there are more than 15000-20000 SPH particles, after some simulationssteps the calculation slows down and gains all memory. Currently I have no idea why!
