VirtualBox gehört zu den beliebtesten Programmen, wenn es darum geht, einen Rechner im Rechner zu simulieren, um zum Beispiel eine Linux-Distribution unter Windows zu installieren. Gerade hat Sun Microsystems die Version 2.0 der Software veröffentlicht, die zahlreiche Neuerungen zu bieten hat. Die Nutzung von VirtualBox ist für Privatanwender und öffentliche Einrichtungen kostenlos.
SIMBRAIN is a free tool for building, running, and analyzing neural-networks (computer simulations of brain circuitry). Simbrain aims to be as visual and easy-to-use as possible. See our design goals. Unique features of Simbrain include its integrated "world components" and its ability to represent a network's state space. Simbrain is written in Java and runs on Windows, Mac OS X, and Linux. Click here for a video introduction to some of Simbrain's features, check out the screenshots, or just download the software and start experimenting. Simbrain is open source, and constantly evolving. We'd love for you to join our team. To discuss any aspect of Simbrain check out the forum.

SimulationX is a graphically-interactive tool for the holistic modeling, simulation and analysis of multi-domain systems from 1D to 3D. Multi-level customizing options and SimulationX’s capability to adjust the model’s complexity by mouse-click allow modeling in every step of the design process. Ready-to-use model libraries, e.g., for mechanics, multi-body systems, power transmission, hydraulics, pneumatics, thermodynamics, and electric drives are written in Modelica language. Libraries are extendable by Modelica-based modeling using the SimulationX TypeDesigner. A comprehensive API supports the integration into any CAE, CFD, CAD or database tool environment. Versatile interfaces offer plenty of opportunities for exporting models in terms of Simulink S-function and C-Code for HiL, RCP and other real-time applications. Different features (tracing, performance analyzer, switchable model complexity) support users in achieving real-time-capabilities.
Dymola provides a powerful object-oriented modeling and simulation tool, which can handle large and complex multi-domain models with no manual equation manipulation.
This library is written in Modelica.
The purpose of this library is to calculate fluid properties from an equation of state (EoS), directly within Modelica and not from an external dll.
It supports EoS of the form f=f(T,d) meaning Helmholtz energy as a funtion of temperature and density.
In addition to all state properties, this library calculates viscosity, thermal conductivity and surface tension.
So far, the fluids n-Butane, R134a and Isobutane are implemented, but not fully validated.
The next fluids to be implemented are probably isopentane, propane, ammonia, CO2 and other possible working fluids for Organic-Rankine-Cycles.
