Speed Dreams is a fork of the open racing car simulator Torcs. It aims at implementing exciting new features, cars, tracks, and AI opponents to make a more enjoyable game for the player, and at constantly improving visual and physics realism. Featuring 44 cars, 44 tracks, and three first-class AI opponents, Speed Dreams is suitable for use as a racing game, as a serious race simulator, and for scientific research.
Widelands is an economic and military simulation game. The map is shown in parallel perspective with 3-dimensional terrain. Buildings and units are animated. The player controls a tribe. Land is claimed and held by military presence and then used to build an economy to support military expansion and confrontation. The project is a work in progress where much remains to be done; computer players and multiplayer are in very early stages of development. Some features that have already been implemented are exploration, fog of war, sound effects, background music, adjustable simulation speed, a few tutorial campaigns, translations to several languages, and a map editor.
Rocket Propulsion Analysis (RPA) is a tool for the performance prediction of rocket engines. By providing a few engine parameters such as combustion chamber pressure, used propellant components, and nozzle parameters, the program obtains chemical equilibrium composition of combustion products, determines its thermodynamic properties, and predicts the theoretical rocket performance. A robust, proven, and industry-accepted Gibbs free energy minimization approach is used to obtain the combustion composition. It can perform analysis of nozzle flows with shifting and frozen chemical equilibrium, optimization of propellant components mixture ratio for maximum specific impulse of bipropellant systems, altitude performance analysis, analysis of nozzle performance with respect to overexpansion and flow separation, throttled engine performance analysis, estimation of test (actual) nozzle performance, and nested analysis: stepping of up to four independent variables (component ratio, chamber pressure, nozzle inlet conditions, and nozzle exit conditions).
RobotMinds is a simulation of a tournament in which programmable robots compete. Each robot's objective is to find its way out of a maze to its home tile. The robots have sensors, and can act on what they sense. There are toxic tiles and radiation from other robots that will destroy robots if exposed to it for too long. The robots can be programmed by way of four screens of checkboxes representing binary switches, so you can program a robot with no knowledge of any programming languages. You can lay walls or full maps to restrict movement.
