Open Source Server Operating Systems Simulation Software

Seagull is a multi-protocol traffic generator. Especially targeted towards IMS, Seagull supports Diameter (RFC3588 and all applications) over TCP/SCTP and IPv4/IPv6 , TCAP (over SS7 or Sigtran), XCAP over HTTP and Radius.

Impact is an explicit Finite Element Program Suite which simulates dynamic impact events. It has a range of elements, contact handling and different material laws. Models can be created, solved and analyzed with the included pre- and postprocessor. Impact is based on an Explicit Time stepping algorithm. These kind of codes are used to simulate dynamic phenomena such as car crashes and similar, usually involving large deformations.

A simple software to read source file of (.src,.svg)Ovation/WDPF's(Emerson Process Management) Graphics Builder/Control Builder. There are also including some useful Ovation Engineering Tools.

Graphical Network Simulator-3 is a network software emulator first released in 2008. It allows the combination of virtual and real devices, used to simulate complex networks. It uses Dynamips emulation software to simulate Cisco IOS.

uspice (Micro-SPICE) is a very small simulator for electrical circuits. The primary platform are low-power devices, such as graphing calculators.

Capsim(r) C Text Mode Kernel(TMK),DSP and communication blocks, topologies, libraries and tools for the development of high performance block diagram digital signal processing and communications systems,built in interpreter for scripting.SystemC support.

CyberUnits is a cross-platform class library for rapid development of high-performance computer simulations in life sciences. It supports modelling for biomedical cybernetics and systems biology with Object Pascal.

GeoGebra is free and multi-platform dynamic mathematics software for learning and teaching geometry, algebra, statistics, and calculus. Download the free software at http://www.geogebra.org. Find the source code at http://www.geogebra.org/trac

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.

NervON is an Open Source project that aims to read and translate human thoughts into a computer. The main objective is to create a virtual world in which millions of people could meet while being totally immersed in this game.

Nuwtun is a Computational Fluid Dynamics code for solving the Euler and Navier-Stokes equations. Code is now hosted at https://bitbucket.org/cpraveen/nuwtun

OFDM IMPLEMENTATION ON AWGN CHANNEL ON CELL BROADBAND ENGINE. This project aims in bringing the single user and multi user ofdm techniques in cell broadband engine which is a multicore architecture.

Spasmos is a Python package that allows scientists to simulate the dynamics of highly collisional plasmas using a number of numerical methods.

VisualPetri is Petri net editor for Windows platform based on GDI Plus library with an integrated simulator. Note: a Petri net is one of several mathematical representations of discrete distributed systems.

WODA (Well Outline and Design Aid) is a groundwater simulator developed at the Group for Numerical Analysis, Jaroslav Cerni Institute, Belgrade, Serbia. WODA does not have its own graphical user interface, but it can work with groundwater models constructed using the freely available Lizza interface, http://www.bioirc.ac.rs/index.php/groundwater-flow-software.
