ITI (Dresden, Germany, www.iti.de/simulation) has its ITI-SIM Version 3.3 engineering simulation software available for on-line tryouts. No need to register eitheróthe package can be tried anonymously for a two-hour shakedown. The session can include loading sample model files, changing parameters, running simulations, and viewing the results. The viewer can also create his or her own models. For help there is a Getting Started tutorial as well as two test choices: Hydraulic Cylinder Drive and Automotive Powertrain and Vehicle Simulation. Once registered, the user can save models, parameters, and results in a free evaluation period for upwards of four weeks. The simulation models are graphic-interactive featuring practical tested models compiled from physical oriented application libraries.
