JMCAD - modeling of dynamic systems JMCAD is an program for the modeling and simulation of complex dynamic systems. This includes the ability to construct and simulate block diagrams. The visual block diagram interface offers a simple method for constructing, modifying and maintaining complex system models. The simulation engine provides fast and accurate solutions for linear, nonlinear, continuous time, discrete time, time varying and hybrid system designs. With JMCAD, users can quickly develop software or "virtual" prototypes of systems or processes to demonstrate their behavior prior to building physical prototypes. The user builds his system model by selecting predefined blocks from a block library and simply wiring the blocks together. Each block of the diagram performs a function. Users can also create custom blocks in Java and add them to the JMCAD block library. JMCAD is a block diagram language for creating complex nonlinear dynamic systems.

GMAT Do you want to go Mars but don't know when to leave or how much to bring? Do you want to study Earth protection by planning a mission to a near-Earth asteroid? Do you want to place a telescope in an orbit that is always looking outwards from the Earth and Sun? The General Mission Analysis Tool (GMAT) is an open-source space mission design tool to help you answer these and many other space flight challenges. GMAT is developed by a team of NASA, private industry, and public and private contributors. It is used for real-world engineering studies, as a tool for education and public engagement, and (after completion of final acceptance testing in Sept. 2013) to fly operational spacecraft.
