SOFEA is a Matlab object-oriented Finite Element toolkit. It includes the book, A Pragmatic Introduction to Finite Element Analysis for Structural Engineers. The toolkit provides linear transient thermal analysis capabilities, with stress analysis and coupled multi-physics coming shortly.
JSBSim is a multi-platform flight dynamics model. The FDM is essentially the physics/math model that defines the movement of an aircraft under the forces and moments applied to it using the various control mechanisms and from the forces of nature. JSBSim has no native graphics. It can be run by itself as a standalone program, taking input from a script file and various aircraft configuration files, or it can be run as an integrated part of a larger flight simulator implementation that includes a visual system. The most notable usage example is the FlightGear simulator. JSBSim models the aerodynamic forces and moments by the classic coefficient buildup method.
Julius MV1 is a showcase application for the Julius framework. It can be used as a fully functional DICOM 3.0 or RAW volume viewer as well as a viewer for large polymesh datasets. It also provides basic data processing features such as volume segmentation or polymesh decimation. Julius MV1 can be used as a basis and testbed for other applications developed with the Julius Framework. The Julius Framework (which comes bundled with MV1) is a general software architecture for medical visualization, simulation, and navigation.
FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
