HyVisual 3.0-beta - Hybrid System Visual Modeler

Block-diagram editor and simulator for hybrid systems. To start immediately by creating a hybrid system, select File, New, Graph Editor from the menu bar. Select Help from the Help menu for instructions on creating a model.
Hybrid systems are systems with continuous-time dynamics, discrete events, and discrete mode changes. This visual modeler supports construction of hierarchical hybrid systems. It uses a block-diagram representation of ordinary differential equations (ODEs) to define continuous dynamics. It uses a bubble-and-arc diagram representation of finite state machines to define discrete behavior.

Below are simple demonstrations of this modeler:

This visual modeler is built using Ptolemy II, which is a software framework developed as part of the Ptolemy project at the University of California at Berkeley. See the Ptolemy Project web page for more information.
