Curve Captor is a free (distributed under GPL) vacuum tube modeling software that brings the advantages of modern computer simulation tools to design of vacuum tube electronics.
runsbml - Pathway Simulation Tool emulates the dynamics of biological pathways by calculating concentrations of biochemical compounds at different times and conditions.
A project to develop in C a command line based assembler/simulator for 8 bit microprocessors used in bare embedded projects. Currently, the motorola 6502 and intel 8051 are supported. Support for other microprocessors may be added.
Put idle assets to work with competitive interest rates, borrow without selling, and trade with precision. All in one platform.
Geographic restrictions, eligibility, and terms apply.
A cross-platform simulator for embedded systems, with a plug-in architecture for adding microcontrollers and other devices. Written in C for maximum compatibilty and speed. Currently has support for AVR AT90S8515 and ATmega128.
Ytk is a Tcl/Tk program which adds menus, buttons and features to the basic command line driven Yorick program and language. It also enables usage of all Tcl/Tk widgets and functions including buttons, sliders, checkboxes, and other typical TK widgets to
Simulator for large neuronal networks using leaky INF as its basic element. Simple few line scripts will enable rapid creation of large networks with different connectivities. Aimed at researchers interested in quickly testing large networks of neurons.
A Java-based mesoscopic, intermodal traffic simulator (MITS), providing a tool to evaluate scenarios (consisting of a road/rail/waterway network topology and load allocation) in terms of throughput, average speeds/travel times, congestion prediction.
A genetic algoritm based system for generating profiled endwalls.
This code is based on the Durham Endwall Design System used to produce endwall designs for low speed linear cascades. It consists of a number of Octave scripts which run mesh generators and flow solvers and uses a genetic algorithm to find the optimal solution.
BigBoy is a three dimensional Finite-Difference Time-Domain (FDTD) simulator for photonics (plasmonics, photonic crystals or high index-contrast structures). Please, refer the successor of this project, GMES (http://sf.net/projects/gmes).
OpenFlood is a fully dynamic 1D / 2D flood simulation engine intended to simulate fluvial and tidal flooding using the Saint Venant and shallow water equations.
This project has adopted a parser for the output of SimIt-ARM's sema_count program. It is useful to get statistically relevant information from the output of a batch run of the simulator.
NetServTester is a small framework to test network service performance,
actually there are plugins for icmp, http and ftp. The results are stored in a database
Freeode is a compiler for the SIML programming language. It is a specialized language to solve differential equations. The compiler creates a python program that uses Numpy and Scipy to do the numerical computations.
