JOS
JOS is an N-body simulation system written in Java
Java Objects Simulation (JOS) is an N-body simulation system written in Java. The idea was to have a simulation system which can use different interaction laws to calculate the force emerging between the objects. Current version implements only Newton's law. For GUI it uses Swing and Java 2D Graphics. GPU version (master branch) does not use Z coordinate of the objects. This is done for faster calculations but can be easily changed. CPU version (arbitrary_precision branch) use Z coordinate... -

CAMPARI
Software for molecular simulations and trajectory analysis
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... -

Sensitizer
A toolset to automate STOP analysis with Zemax OpticStudio
.... The core data structure of SENSITIZER is an optical group, which can be any optical surface in the lens file or a set of subsequent surfaces. These groups will be perturbed by varying their positions relative to the rest of the system (rigid-body-motions) and/or by adding Zernike shape deformations on their front surface. After a certain perturbation is applied, ZOS runs (sequential) raytracing to compute the optical performance such as centroid displacement or wavefront error. -
