We are proud to introduce version 5 of CAMPARI. We have added a number of new features, most notably a Python interface for interpreting user-supplied code (with the help of ForPy), a novel trajectory storage standard (with the help of libpqxx/PostgreSQL), and a module for performing transition path theory. Naturally, CAMPARI continues to provide the reference implementation of the ABSINTH force field paradigm and implicit solvation model. CAMPARI is a joint package for performing and analyzing molecular simulations, in particular of systems of biological relevance. It focuses on a wide availability of algorithms for (advanced) sampling and is capable of combining Monte Carlo and molecular dynamics in seamless fashion. CAMPARI offers the user a very high level of control over all implemented features. For more information and features, please refer to the project's homepage at http://campari.sourceforge.net/V5

A package for transient and steady state simulation of organic solar cells.

'atlc' is a CAD package used for analysing and desiging electrical transmission lines of arbitrary cross section. Also for the design of directonal couplers. Some parts are CPU intensive, so multiple CPUs are supported.

I.S.A.A.C.S. Interactive Structure Analysis of Amorphous and Crystalline Systems is a cross-platform software developed to analyze the structural characteristics of three-dimensional models built by computer simulations.

The Ground Station Software Suite projects aims at providing free, useful software tools for ham radio operators. Currently, this projects hosts the Grig communication radio control. The source repository has been moved over to github.

Wcalc is a tool for the analysis and synthesis of electronic components. Some of the models include coupled microstrip lines, single layer air core solenoid inductors, etc. Wcalc can analyze the electrical parameters based on the physical dimensions a

An application programming (API) and graphical user interface (GUI) to facilitate the use of PENELOPE's program PENEPMA.

Brax is a fast and fully differentiable physics engine for large-scale rigid body simulations, built on JAX. It is designed for research in reinforcement learning and robotics, enabling efficient simulations and gradient-based optimization.

Antenna Radiation Diagram Plotter - Polar plots of measured EM emission, with a proper radial axis scaling and span. Three source files (plain text) can be loaded and plotted at the same time. Export to file or clipboard.

Airfoil optimization using the highly-regarded Xfoil engine for aerodynamic calculations. Starting with a seed airfoil, Xoptfoil uses particle swarm, genetic algorithm and direct search methodologies to perturb the geometry and maximize performance. The user selects a number of operating points over which to optimize, desired constraints, and the optimizer does the rest.

SeaBreeze is a device driver library that provides an interface to select Ocean Optics spectrometers. It is written in C/C++ and builds and runs on Windows (XP/7/8), MacOSX, and Linux (x86/x64/ARM).

WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics of distinguishable particles. It can be used to solve single or coupled time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations, partly also classical or quantum-classical Liouville equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can be used to simulate modern experiments involving ultrashort light pulses in photo-induced physics or chemistry, including quantum optimal control. Allowing for visualization of dynamics 'on the fly', WavePacket is easy to use . First established in 2004, the present Matlab version is in a stable, mature state. Further development mainly by Burkhard Schmidt at WIAS and FU Berlin.

Blitz++ is a C++ class library for scientific computing which provides performance on par with Fortran 77/90. It uses template techniques to achieve high performance. Blitz++ provides dense arrays and vectors, random number generators, and small vectors (useful for representing multicomponent or vector fields).

The repository has been moved to: https://github.com/wojdyr/fityk. Fityk is nonlinear curve-fitting and data analysis software. It is specialized in fitting peaks (bell-shaped functions like Gaussian, Loretzian, Pearson7, Voigt) to experimental data.

Wcalc is a powerful arbitrary-precision calculator. It has standard functions (sin, asinh, logtwo, floor, etc), many pre-defined constants (pi, e, c, etc.), variables, "active" variables, command history, and hex/octal/binary i/o, conversions, and more

Aciqra is a virtual planetarium and sky mapping program which tracks celestial bodies including planets, deep sky objects and stars to an accuracy of a fraction of a degree for thousands of years into both the future and the past. It includes the 2.5 million stars of the Tycho-2 catalog supplemented by data of 120,000 stars from the Hipparcos catalog, 13,000 deep space objects from the NGC and IC catalogs and a large number of asteroids and comets from the Minor Planet Center. The program is platform-independent and can be made to work on most modern computers that support OpenGL.
