Open Source C Simulation Software for BSD

ASCEND is a modelling environment and solver for large or small systems of non-linear equations, for use in engineering, thermodynamics, chemistry, physics, mathematics and biology. Solvers for both steady and dynamic (NLA & DAE) problems, are provid

PySCeS is the Python Simulator of Cellular Systems. For a network of coupled reactions it does a stoichiometric matrix analysis, calculates the time course and steady state, and does a complete control analysis.

NanoHive is a modular simulator used for modelling the physical world at a nanometer scale. The intended purpose of the simulator is to act as a tool for the study and development of nanotech entities. The project will also focus on the simulation of complex biological applications such as Targeted Drug Delivery by simulating nanowires, magnetic nanoparticles and others. Updates will follow from January 2017.

This software has moved to http://www.poissonboltzmann.org/.

The EvoGrid is an effort to develop a distributed simulation system to simulate potential pre-biotic chemical environments.

Hy3S uses advanced MPI parallelized hybrid stochastic simulation methods to quickly compute the dynamics of biochemical networks with thousands of species/reactions. Many features included (see Home Page). An easy-to-use GUI (Matlab req) is included.

PUPIL (Program for User Package Interface and Linking), is a software environment that allows developers to link quickly and efficiently together multiple pieces of software in a fully automated multi-scale simulation. More specifically, it supports QM/MM MD simulations where the user might choose among any of the different MD engines and QM engines, which are connected to PUPIL as external programs through a tiny specific interface. One of the main advantages here is that the user can use most of the functionalities that may have those external programs interfaced without the necessity to be reimplemented again on independent interfaces. In fact, this simulation interface concentrates all the common code involved in the coupling terms of the QM/MM approach.

Stochastic simulator for signaling pathways occuring in biological cells. Handles reaction-diffusion processes in 3D tetrahedral meshes. Please check our new repository: https://github.com/CNS-OIST/STEPS

A family of programs for building coarse-grained models (eg. of macromolecules), manipulating them (geometrical transformations and more) and calculating their X-ray scattering patterns (1D and 2D too). Uses PVM for parallelization.

ISL Equilibrium Calculator,which process solid-liquid equilibrium calculation by using Harvie extended Pitzer's ion interaction electrolyte solution model and particle swarm optimization Gibbs free energy minimization (GEM). ISLEC is an efficient tool for solid-liquid equilibrium calculation, and can simulate the crystallization path of seawater and salt lake brines. ISLEC is suitable for related researches and process design.

MDcore is an Open-Source library implementing the core functionality of a Molecular Dynamics engine. The engine is inherently multi-threaded and runs efficiently on multi-processor/multi-core shared-memory architectures.

runsbml - Pathway Simulation Tool emulates the dynamics of biological pathways by calculating concentrations of biochemical compounds at different times and conditions.

The Gecko Hamaker open-source software project is a full implementation of the fully retarded Lifshitz formulations for isotropic and anisotropic plane-plane and cylinder-cylinder interactions with intervening interlayer materials, planar systems of up to 99 layers, and graded interfaces for the modeling of grain boundaries or other continuously changing systems, accompanied by a database of material optical properties spectra. The machine-readable optical property database is available for download and as a web service and makes available the full spectral optical properties of over 150 materials from both ab initio calculations and experimental measurements.
