Modeling and Simulation with Modelica* in SimulationX
ITI actively supports the development of the object-oriented model description language Modelica as a standard for physical modeling.
The language definition and Modelica standard library are disposable and are enhanced and developed by the Modelica Association. From SimulationX version 3.3 a Modelica Edition is availabe dedicated to Modelica experts. The corresponding tutorial is available in our download area under tutorials and viewlets.
Use of Modelica Models
Models of the Modelica standard library and models based on the language definition of Modelica (current version 3.0) are executable in SimulationX. Basically the modeling and simulation processes in SimulationX are the same as in Modelica: load of a model file, change of parameter in a graphical user interface, start of the simulation and use of the tool infrastructure to display the simulation results. The current Modelica libraries are displayed in the SimulationX tree. For the graphic display of the models and their connections SimulationX uses the graphics and ViewInfo annotations of the Modelica text. The SimulationX analysis processes are also applicable for the Modelica models.
User-defined Modelica models
The Development of new models can be made with every suitable Modelica tool or Editor. Once the model file (e.g. package) is stored in the Modelica path of SimulationX the new model is available in the library tree. Users who prefer a structured and guided model development work with the SimulationX TypeDesigner. This is an assistant who systematically guides through every step of the model development. TypeDesigner supports the user in designing and working with every type of classes in Modelica (model, connector, record, block, function, package).
Modelica Multi-body Mechanics
For the modeling of multi-body systems SimulationX offers one or more 3D views. The figure shows the example “SpringDamperSystem” of the Modelica Multi-body library in the SimulationX environment. As computation results the natural frequencies are shown.
