Hi everyone. My name is Robert Palmer and I am going to give you a quick introduction to what’s new in SystemModeler 4. First down in our list of new features is new and improved built-in libraries. In SystemModeler 4, you’ll find that we’ve updated the built-in Modelica Standard library to version 3.2.1, which includes new libraries and components from digital circuits, complex signals, heat dissipation, and more. or instance, you’ll find the digital library for digital electronics, the quasistationary library for efficient approximate modeling of electrical circuits with sinusoidal currents and voltages, and the fundamental wavelength library for modeling multiphase electrical machines. You’ll also find that the rotational and translational mechanics libraries have been updated to support thermal ports, making it more convenient to capture heat losses in your mechanical models. To find demonstrations of what can be done with all these new libraries and components you can always check out our industry examples webpages. With SystemModeler 4 we’ve also introduced a major new thing called the SystemModeler Library Store, from which you can download and automatically install additional paid and free model libraries. All of these libraries have been tested and verified to work with SystemModeler 4 and we’re continuously working with developers to bring you new and updated libraries as well as to make sure that these libraries come with high quality documentation and are easy to use. The libraries currently available at the store include the Hydraulic and Smart Cooling libraries and the Biochem, System Dynamics and Planar Mechanics libraries. On the following slides I will briefly go through the main features and uses of each library and some of the libraries will then be demonstrated in more detail in the upcoming presentations. Once again you can find example models from these libraries on our industry examples webpages and some of the examples can also be reached directly from the Library Store. So first out among these libraries we have the Hydraulic library, which is a commercial library designed from modeling hydraulic systems and, for instance, aircrafts, cars, heavy equipment and process industries. And it includes a number of different hydraulic components, such as cylinders, tanks, pipes, etc. Next we have the Smart Cooling library, which is also a commercial library. It can be used to efficiently model cooling systems in, for instance, cars, heavy equipment, and aircrafts. And includes components such as cooling fans, pipelines, water pumps, and heat exchangers. Possible applications of both the Hydraulic and Smart Cooling libraries will demonstrated by my colleagues in the next two presentations. The Library Store also includes a number of free libraries and among these we’ll find an updated version of the Biochem library used for modeling, simulation and visualization of biochemical reaction networks. The library can be applied in areas such as systems biology and pharmacokinetics and include common biochemical model components such as compartments, reactions, and substances. Using these libraries it is also possible to import and export models defined in the systems biology mark up language to and from SystemModeler. To give you an example of how this library can be used, we can have a quick look at this pharmacokinetic model of an MRI contrast agent. The model can, for instance, be used to simulate and investigate differences between people with varying stages of liver fibrosis. Among the free libraries we also have the Planar Mechanics library, which primarily has been developed to be used in teaching mechanical engineering courses. The library focuses on 2D mechanical systems and includes components such as dampers, revolute joints and wheel models. As an example, we can look at this model of a pendulum and slider-crank from our examples collection. This model can also be nicely animated and made interactive using the link between SystemModeler and Mathematica. Finally, we have the System Dynamics library, which, as the name implies, is based on the systems dynamic methodology. The library includes level and rate components and can used to build sociotechnical models of, for instance, energy markets, disease propagation or logistics systems. This model describing the spread of an influenza virus in a population is one example of how this library can be used. OK, so now we have covered everything new in SystemModeler 4 related to libraries. Other important new features include an improved user interface in Model and Simulation Center, allowing for things like structuring model parameters in groups and tasks, better control of simulation settings and selecting objects in 3D animations. Moreover, in SystemModeler 4 you’ll find a completely new Documentation Center where you can get the answers to many of your SystemModeler-related questions. The Documentation Center includes built-in resources such as videos, tutorials, modeling advice, user guides, library and component documentation and also the Modelica by Example book by Michael Tiller. You can reach the Documentation Center from the “Help” menu in Model or Simulation Center or you can just right click any library or model in the “Class” browser and view its documentation. You can also search for topics, libraries, or models directly using the “Search” field and you’ll find that the documentation is extensively cross-linked. For instance a very useful feature is the “used in examples” and “used in components” sections, which gives you links to all available examples and other models making use of a specific class. In SystemModeler 4, we have also improved connectivity and deployment options. Most importantly, we have added support for exporting models using the functional mockup interface, FMI, which is a newly developed industry standard for model exchange. You can therefore export your SystemModeler models to many other software systems. The integration between SystemModeler and Mathematica has also been improved and includes many new features, such as functions for automatically creating SystemModeler models from equations or controlled system models in Mathematica. Moreover, SystemModeler objects in Mathematica now use model diagrams as their visual representation. Diagrams can be used together with other graphics in Mathematica and they can also be animated to show system behavior. Both connectivity and deployment and the integration with Mathematica are areas that will be covered more extensively in the upcoming presentations. So, we have now reached the end of my presentation and to conclude I just want to quickly recap the main points of the things that we’ve looked at. New features in SystemModeler 4 include updated and new built-in libraries as well as new add on libraries, which can be reached from the SystemModeler Library Store. We have improved user interface and overall performance of Model and Simulation Center as well as the new Documentation Center. We also have FMI export to deploy models and use them in other software tools. And finally, we have deeper integration with Mathematica. I hope you’ll find all these new features useful and thank you very much for listening.
