Runge is an Interactive Solver for Systems of Ordinary Differential Equations. It solves initial value problem (aka Cauchy problem). Few advantages Runge provides: It's fast. It utilizes BLAS and LAPACK libraries optimized for modern multi-core processors. It's interactive. It allows you to start a solution by mouse click on a plane. It's precise. It uses Runge Rule to adjust step length to satisfy required precision on each step. It's effective. When it needs to compute derivatives (Jacobian matrix, for example) it does that analytically, i.e. without using numerical methods. It's portable. It works on Windows and Linux 32 and 64 bit and Mac OS X 64 bit. It's open. It allows you to implement and embed your own algorithms (aka "solvers"). It's easy to use. It allows to export results to MS Excel and MATLAB. It's multilingual. It currently supports Englis and Russian languages. It's free. It's distributed under the Boost Software License.

This project is for particle accelerator start-to-end simulation. The project contains software infrastructure for setting up model run as service/client mode.

S3d is a mesh generating machine.

SAC (Symbolic Analysis and Control) is a toolbox for people working in control theory. It will help to the analysis and synthesis of nonlinear systems described by state equations (with or without delays).

An open source framework for mac os x that allows for crystallographic calculations and symmetry information for point groups and space groups.

libscmodcam provides an easy way for Linux applications to capture long-exposure frames from a Philips USB webcam (if it is supported by the PWC kernel driver). Currently only the SC1 modification and the C++ language are supported.

The Software for Controlling Testing Equipment - has been designed to automate data acquisition and equipment control. Written in Perl, uses the SCPI language to communicate with instruments via RS-232 (serial) or USB ports.

Used in physics, made to make calculating long variance and standard deviation equations simpler.

Routines and graphical interface to control and test AMS TOF Electronics

A spectral element method for 2D wave propagation and fracture dynamics, with emphasis on computational seismology and earthquake source dynamics.

SFrame is a C++ framework built around the ROOT libraries for analysing particle physics data. It gives a very high performance for processing data, by allowing the user to run his/her code on a distributed farm of machines.

Windows program to analyse data recorded by popular ion trajectory simulation software SIMION.

The SIMP/STEP platform provides a fast, efficient, portable abstract framework for interactive and scripted cellular automata and lattice gas computing in the Python environment. SIMP provides a high-level 'programmable matter' laboratory built on

This unit conversion program is based on the latest standard of International System of Units (SI) and NIST Special Publication 811 (1995 Edition) and provides many more conversions. Licensed under GPL3. Written in Python and Qt toolkit.

The software package SINSEL («SImulator New of Solution Equation of Landau») is designed to fit a one and multiple oscillating peaks spectrums with the new solution of the kinetic equations of Landau.

SMMP (Simple Molecular Mechanics for Proteins) is a program library for protein simulations with an emphasis on advanced Monte Carlo algorithms. It includes various force fields to calculate the energy of a protein and protein-protein interactions.

Sandia National Laboratories’ (SNL) environmental assessment modeling tool helps optimize the design of MHK-turbine array layouts within ocean, tidal, and river systems to balance energy generation efficiency with environmental considerations. The new tool, SNL-EFDC, is an augmented version of US EPA’s Environmental Fluid Dynamics Code (EFDC) and includes; (1) a new module that simulates energy conversion (momentum withdrawal) by MHK turbine-like devices including commensurate changes in the turbulent kinetic energy and turbulent kinetic energy dissipation rate, (2) new, advanced sediment dynamics routines, and (3) augmented water quality modules. SNL-EFDC has been verified and validated against flume measurements of flow around sub-scale turbines and actuator disks.

An SNTP client for Virtual PC. It is for machines that do not have a sane time and a working hardware RTC. It synchronize the system time frequently with a nearby NTP server. It uses settimeofday(). It is based on RFC 1769 and RFC 1305.

SPARTA is a parallel DSMC code for performing simulations of low-density gases in 2d or 3d. Particles advect through a hierarchical Cartesian grid that overlays the simulation box. The grid is used to group particles by grid cell for purposes of performing collisions and chemistry. Physical objects with triangulated surfaces can be embedded in the grid, creating cut and split grid cells.
