From MVsoft:

Model Vision Studium is an integrated graphical environment for fast and easy visual designing of interactive models of complex dynamical systems and experimenting on them. Key features: creating models doesn't require any programming; uniform approach to modeling of discrete, continuous, and hybrid systems; natural visual formalism for behavior description - hybrid state chart; object-oriented modeling support; matrix and vector data types; supports systems of differential, algebraic, and differential-algebraic equations with derivatives of the second order and not resolved concerning derivatives; automatic creation of equivalent mathematical model of entire system and further translation to computable form; visual interactive model is a separate executable file; wizards for easy 2D and 3D-animation; and automatic choice of the numeric method. Tens of examples are included. Version 4.1 adds a new equation editor; simplification of the integrated environment interface; changes in visual model and changes in the source language.
