With this program dynamical models can be constructed and used for simulations. Dynamical systems react time dependend. If their characteristic parameters are plotted against time, it is easy to recognize the behaviour of the system. With Modus certain symbols can be connected with each other and used to represent dynamical systems as a graph on the computer-screen. The structur diagrams thus formed are then converted to corresponding equations by the program.
Different methods exist.
One can also construct model components which can be connected with each other. If you want to work with the model you should obtain the program and the detailed description from the publisher. In eight steps you are introduced into the handling of the program. On the program disks are also a number of examples, among others the predator-prey model describing oscillations between populations of predator and prey.
