Rigs of Rods is an open source simulator for soft-body physics What makes Rigs of Rods different to most simulators is its unique soft-body physics simulation: Objects are simulated in real-time as flexible soft-body objects, resulting in a very realistic simulation which entirely depends on the physical construction of the object.

OSP EJS Modeling Overview

In addition, many traditional science courses now have computational components, as more and more faculty become convinced of the importance for every science graduate to be 'computer-literate'. Step. Step Description Step is an interactive physics simulator. It works like this: you place some bodies on the scene, add some forces such as gravity or springs, then click "Simulate" and Step shows you how your scene will evolve according to the laws of physics. You can change every property of bodies/forces in your experiment (even during simulation) and see how this will change the outcome of the experiment.

With Step you can not only learn but feel how physics works ! Features StepCore Library StepCore is the physical simulation library on which Step is based. Details of package xball in sid.

Abstract Alliance is a complete set of free cad tools and portable libraries for vlsi design.


It includes a vhdl compiler and simulator, logic synthesis tools, and automatic place and route tools. A complete set of portable cmos libraries is provided. Alliance is the result of a twelve year effort spent at SoC department of LIP6 laboratory of the Pierre & Marie Curie University (Paris VI, France). Alliance has been used for research projects such as the 875 000 transistors StaCS superscalar microprocessor and 400 000 transistors ieee Gigabit HSL Router.

Release 3.3a for Windows 95/98/Me and NT 4.0/2000/XP Release 3.3a of Home Planet, a comprehensive astronomy / space / satellite-tracking package for Microsoft Windows 95/98/Me and Windows NT 4.0/2000/XP and above, is now available; see details at the end on how to download and install the software.

Home Planet Release 3.3a

Release 3.3a of Home Planet is a native 32-bit Windows application which cannot be used on Windows 3.1; if you have such a system, download Home Planet Release 2, which remains available. Home Planet is in the public domain; it is free software. It is not shareware—you don't have to register it or pay anybody anything, and the version you download is fully functional as soon as you install it. Moontool for Windows. By John Walker March 16 MIM Moontool for Windows is a Microsoft Windows application which calculates the phase of the Moon at either the current time or at any user-specified time and displays a picture of the Moon at the correct phase, either as a system tray icon or in an open window.

Moontool for Windows

Moontool Display When the Moontool window is open, it displays comprehensive information about the Moon. When Moontool is minimised, it becomes an icon in the system tray which shows the current phase of the Moon; double clicking its icon restores the original display. If you'd like a permanent Moon phase display in the system tray, add a shortcut to Moontool to your StartUp folder with the Run property set to Minimized. Moontool allows the information displayed in the open window to be copied to the clipboard as a bitmap, permitting you to paste it into another document. KAstrhorloge for Linux and KDE. KAstrHorloge is an astronomy software for Linux & KDE.

KAstrhorloge for Linux and KDE

KAstrHorloge is provided with a 10000 stars database. For any of these stars or planets, the software can compute its position in the sky of your observation site. It displays the object location both in a map and in terms of coordinates (alpha and delta) For each star or planet, you can add your own comments (for example, some physical data, or observation comments) and even a CCD image of the object ! All functions of KAstrHorloge are intuitive and easily accessible, so you can use this software without reading the doc ! Good observations ! Eric. How to download this software Karchiver is a free software, releaded under the GNU General Public Licence, version 2 or later. Nova. Orbit Reconstruction, Simulation and Analysis Website. Aciqra: A Virtual Sky Map. KStars. Description KStars is free, open source, cross-platform Astronomy Software.


It provides an accurate graphical simulation of the night sky, from any location on Earth, at any date and time. The display includes up to 100 million stars, 13,000 deep-sky objects,all 8 planets, the Sun and Moon, and thousands of comets, asteroids, supernovae, and satellites. For students and teachers, it supports adjustable simulation speeds in order to view phenomena that happen over long timescales, the KStars Astrocalculator to predict conjunctions, and many common astronomical calculations.

For the amateur astronomer, it provides an observation planner, a sky calendar tool, and an FOV editor to calculate field of view of equipment and display them. Have a look at the Feature listing for more. Download KStars 2.7.0 is released on Oct. 28th, 2016 and can be installed on a number of platforms, most notably Microsoft Windows and GNU/Linux. For other platforms, see our Installation Page for instructions. Features. Gpredict: Free, Real-Time Satellite Tracking and Orbit Prediction Software. Mars Simulation Project.

In addition the position of planets, asteroids and comets are shown. [XSTAR] The XStar N-body Solver. XStar is a Unix program that simulates the movement of stars.

[XSTAR] The XStar N-body Solver

It starts by putting a bunch of stars on the screen, and then it lets the inter-body gravitational forces move the stars around. The result is a lot of neat wandering paths, as the stars interact and collide. Figuring out what paths these stars should take is called the "N-Body Problem", and when there are more than 3 stars involved (N>3), this can be a very hard problem to solve. Celestia: Home.
