Polycrystal generation and meshing.
Neper is a software package for polycrystal generation and meshing. It can deal with 2D and 3D polycrystals with very large numbers of grains. Its main features are: - Generation of polycrystals from (experimental) morphological properties; - Generation of multiscale microstructures; - Generation of periodic or semi-periodic microstructures; - Meshing into good-quality elements; - Meshing with cohesive elements at interfaces; - Visualization and analysis of the tessellations and meshes. Neper is built around three modules: generation, meshing and visualization. All the input data are prescribed non-interactively, using command lines and / or ASCII files. Neper can be compiled and run on any Unix-like system.

A code primarily aimed at DNA and RNA coarse-grained simulations
oxDNA is a simulation code that was initially conceived as an implementation of the coarse-grained DNA model introduced by T. E. Ouldridge, J. P. K. Doye and A. A. Louis (http://dx.doi.org/10.1063/1.3552946). It has been since reworked and it is now an extensible simulation+analysis framework. It natively supports DNA, RNA, Lennard-Jones and patchy particle simulations on both CPUs and NVIDIA GPUs.

Routines for wavefront propagation in IDL, Matlab, and Python
PROPER is a library of routines for the propagation of wavefronts through an optical system using Fourier-based methods. It was developed at the Jet Propulsion Laboratory for modeling stellar coronagraphs, but it can be applied to other optical systems were diffraction propagation is of concern. It is currently available for IDL (Interactive Data Language), Matlab and Python (2.7 & 3.x). It includes routines for generating complex apertures and obscurations and aberrations (Zernike & PSD-defined). It includes a model of a deformable mirror for wavefront control. The routines perform near and far field propagation with automatic selection of propagators. The latest version is v3.0a. released on 24 Jan 2018.

A program for fitting structural models to small angle scattering data
SASfit has been written for analyzing and plotting small angle scattering data. It can calculate integral structural parameters like radius of gyration, scattering invariant, Porod constant. Furthermore it can fit size distributions together with several form factors including different structure factors. Additionally an algorithm has been implemented, which allows to simultaneously fit several scattering curves with a common set of (global) parameters. This last option is especially important in contrast variation experiments or measurements with polarised neutrons. The global fit helps to determine fit parameters unambiguously which by analysing a single curve would be otherwise strongly correlated.
