Open Source Linux UML Tools

An optimized C library for numerically solving exterior ballistics problems. It supports standard drag models (Drag Functions G1-G8). The solution method is the common "3 degree of freedom" analysis found in many commercial programs.

DAE Tools is a cross-platform equation-based object-oriented modelling, simulation and optimisation software. It is not a modelling language nor a collection of numerical libraries but rather a higher level structure – an architectural design of interdependent software components providing an API for: - Model development/specification - Activities on developed models, such as simulation, optimisation, sensitivity analysis and parameter estimation - Processing of the results, such as plotting and exporting to various file formats - Report generation - Code generation, co-simulation and model exchange The following class of problems can be solved by DAE Tools: - Initial value problems of implicit form - Index-1 DAE systems - With lumped or distributed parameters - Steady-state or dynamic - Continuous with some elements of event-driven systems

EcoLab is a C++ based Agent Based Modelling system, with emphasis on high performance computing for scaling to large simulations.

That project aims at providing a clean API, and the corresponding C++ implementation, for the basis of Airline IT Business Object Model (BOM), ie, to be used by several other Open Source projects, such as RMOL, Air-Sched, Travel-CCM, OpenTREP, etc.

Behavioural Hybrid Process Calculus (BHPC) simulation tool.

CASUP is a Cellular Automata (CA) library for HPC and supercomputers. It can be used in materials science (microstructure evolution, grain coarsening, fracture etc.), physics (Ising magnetisation) and for many other CA. If you use the library, please reference it as: A. Shterenlikht, L. Margetts, Three-dimensional cellular automata modelling of cleavage propagation across crystal boundaries in polycrystalline microstructures, Proc. Roy. Soc. A 471:20150039, DOI: http://dx.doi.org/10.1098/rspa.2015.0039. CASUP can be linked with FE (e.g. MPI FE library ParaFEM, http://parafem.org.uk) for a multi-scale multi-physics CA-FE framework. CASUP extensively uses Fortran 2008 and 2018 coarrays, as well as MPI, OpenMP and do concurrent. CASUP can be used with Cray, Intel and GCC/OpenCoarrays compilers. Scaling beyond 100,000 cores on Cray XC30 was demonstrated.

Calculation of camshafts - allows to define a camshaft profile on the set trajectory which should provide the given mechanism. The trajectory can be set graphically, co-ordinates or function.

JAS-mine is a Java platform that aims at providing a unique simulation tool for discrete-event simulations, including agent-based and microsimulation models. With the aim to develop large-scale, data-driven models, the main architectural choice of JAS-mine is to use whenever possible standard, open-source tools already available in the software development community. It has built-in utilities for communicating with an underlying relational database. In addition, the platform provides standard tools which are frequently used both in agent-based modelling and dynamic microsimulations, like design of experiments (DOE), run-time monitoring and visualization with plots and graphs (GUI), I/O communication and statistical analysis. JAS-mine source code can be found on GitHub, with the core repository at: https://github.com/jasmineRepo/JAS-mine-core and the GUI repository at: https://github.com/jasmineRepo/JAS-mine-gui

Quan is designed to model physical quantities in C++ programs. Advantages include automated dimensional analysis checking, automatic unit conversions, self documentation of code.

That project aims at studying the impact of IT systems interactions on traveller demand and airline revenues. Passenger demand is generated (Monte Carlo) and injected into simulated CRS and airline IT systems. Differential analysis is then performed on various changes compared to a bottom line scenario.

Cppfunct implements run-time C++ function objects, with creation, invocation, manipulation, and combination. The function object concept abstracts ways to parameterise other classes beyond simple static values.

C++ library for calculating the light propagation through large and very small structures (sub wavelength). The used method is the Fourier Modal Method. It can be solve one and two dimensional dielectric structures such as gratings, waveguides etc.

The fast2armc program translates source code of a counter automata model for FAST(er) tool to the ARMC prolog syntax.

A portable, high-level 3D engine with an emphasis on generality. So far it is mainly used in CAD applications in need of geometrical constraint solving and other geometrical methods. FreeSG is designed as an integrable component and not a framework.

Generates and simulates realistic traffic patterns. Focuses on detailed zone model & simplistic characters living at designated zones. Easy-to-use plugin for city and traffic simulators. Demo uses Ogre 3D.

This project documents the development of a suite of ns2 grid network simulators that was done as part of the EC-GIN project. The aim is to refine and develop these simulators to provide input to the larger ns2 and grid simulation community.

GridABM is an easy-to-use toolkit to develop high-performance agent-based models (ABMs) in Repast. GridABM facilitates large-scale simulation of ABM on multicore computers, local computing clusters, or computational grids.

ISIADIS: development environment for hierarchical software systems. ISIADIS allows prototyping, development and running software systems that are based on hierarchical (tree-like) architecture.

Japrosim is a java library for both discrete event and continuous simulation. GUI for modeling and automatic code generation are offered. An explanation module is integrated. Models are described in XML and owl for interoperability.

JPowerFlow - a steady state electric power system power flow solver.

Java Fuzzy Editor is a basic editor to allow creation of fuzzy based rules. It will save to serveral formats including to source code in several languages.

LTSA it's a tool that supports LTS construction, elaboration and annalisys.

The Location Containment Object Model(LCOM) is a simulation framework written in Python. LCOM provides a rule-based solution to handling partial object containment, object migration, message passing, and simulation observation.
