Free Demo for ModelOpt

ModelOpt is a an optimization application for minimizing cost functions or deviations from a design or measurement value. It uses Dymola/Modelica for modeling and target function definition as well as for simulation (from version Dymola 6.1 to the latest version). A simple and intuitive graphical user interface guides the user step by step through an optimization project.

The demo software for Windows operating systems is available for free.
