Partgen is a simple particle system generator and simulator. It's intended to have a 3D scene description language, and batch processing mode. Support for some scripting languages like ruby is also planned

An automatic 2D Delaunay mesh generator and solver for Finite Element Analysis. Can solve 2D field problems (Poisson and Helmholtz Equations). Can use LAPACK/ARPACK solvers producing OpenGL/Postscript output. Uses C/GTK/GTKGLExt/MFC. Runs on Win32/Unix.

Automated peak fitting and spectrum calibration program.

Real-time data visualization. Graphically view your data as it's being generated. Peakster is a very intuitive GUI written entirely in Python, which monitors data at regular intervals and uses gnuplot to render 2D, 3D and superimposed plots.

a library which i hope to write to compute high precision aerodynamic and electrodynamic equations

A generalized and flexible pipeline management software.

This program allows to perform a structural cluster analysis of atomic trajectories obtained, e.g., from molecular dynamics simulations. At variance with other approaches, it is possible to analyse also processes in solution, e.g., chemical reactions in liquid water, since the distance metric is based on a Permutation Invariant Vector (PIV) that is symmetric under exchange of identical atoms or molecules, including on the same footing both solute and solvent degrees of freedom. The approach is general and the definition of PIV only requires to specify the range of interatomic distances that is relevant for the process under study. Alternatively, also the SPRINT topological coordinates can be employed, that are particularly suited for nanostructures. The output is a partitioning of the trajectory into a few structural clusters (i.e., sets of frames), allowing for simpler analysis and visualization. Please read and cite Gallet & Pietrucci, J. Chem. Phys. 139, 074101 (2013)

Particle image velocimetry (PIV) is an optical method of flow visualization. pivonvideo combine together several tools to automatize PIV analysis of whole video extracts, performing image extraction, transformation, analysis and result visualization.

The Plot.py project tries to supply a measurement data visualization and treatment framework being easy to use while keeping the freedom for advanced users to execute additional data treatment algorithms. Plotting is done via gnuplot and the script used to produce the graphs can be exported for later use/changes. Many raw experimental data types (mostly of x-ray and neutron scattering experiments) are supported with more to be added on user request. The data treatment includes non-linear fitting, integration and differentiation, peak-finder and more. User python code can be executed in the integrated IPython console.

Program for solving pnp equations

Maximum packing densities for individual, polydisperse (diameter), ellipitic platelets and stacks of them (max 5 platelets per stack implemented). Size fractionating for stacks (platelets with diameters below a cut-off diameter remain as individual platelets all others assemble in stacks) can be included. Considers only hard interactions and assumes spherical exclusion volumes.

**(9 march 2016) this project is continued on github : http://jaapkroe.github.io/polypy ** Python script to analyze (shortest-path) rings in structures read from xyz-files. It can be useful for example to identify defects in crystal structures or molecules.

The potfit code uses the force-matching method to generate effective potentials from ab-initio reference data.

Library for manipulating and exchanging powder diffraction data files in various formats.

A C++ class to enable prediction of the reflectance spectrum of two overprinted inks (i.e., solids), using the inverted Viggiano trapping equation.

PSI is an open-source program for computing molecular properties using high-accuracy, ab initio, quantum mechanical models.

For a given signal, pstool calculates a one-sided power spectrum, i.e. the portion of a signal's power falling within given frequency bins. This is done by employing a one-dimensional real-to-complex FFT routine on an MPI cluster.

pyBallistics is a graphical small arms ballistics program used to calculate ballistic coefficients, and model bullet trajectories. Future improvements will be a reloading database, and web links to industry reloading data.

This program allows to design a x-ray spectrometer. A particular aspect is the large options of crystal shape. The source, crystal and detector are freely positionnable in 3D space (allowing to check the effect of misalignment)

A python class that permits the use of consumer sound cards to capture signals from a home made EFNMR kit

pyitc is designed for processing and analysing isothermal titration calorimetry experimental data (Microcal instruments).

This project is a collection of python modules for modelling various optical systems. It presently consists of pyFresnel and pyQW. pyFresnel models optical properties of dielectric layers and includes a thin film model (unlike the many other codes out there this can also handle uniaxial layers as long as the optical axis is aligned with the stack growth direction). pyQW models very simple (n-doped) quantum well structures and their intersubband transitions.

The pySpec project is a set of data analysis routines written in python for analysis of x-ray diffraction data produced by the SPEC X-Ray Diffraction and Data Acquisition software. This repo has moved to : https://github.com/stuwilkins/pyspec
