SimApp is a dynamic simulation application created for modeling systems in the time and frequency domains. SimApp offers significant simulation power at a reasonable price, while reducing learning time. Once the dynamic behavior is understood, changes to the system can be made or control systems can be designed to make the system perform as desired.The computer simulation model is built visually through block diagrams. These signal-flow diagrams can represent a virtually unlimited range of systems. You may also elect to represent models in a matrix form (continuous or discrete), or as difference equations for digital controllers. You can use SimApp to evaluate analog feedback systems or digital systems implemented in a controller.

SimApp contains many features that help you grow the model sophistication to the level needed for realistic results. Non-linear elements and custom inputs bring reality to the models. SimApp can also help you hide model complexity by building commonly used elements or subsystems into custom blocks. In this way you can also make SimApp your own - and uniquely tune it for your field of expertise.Time plots show the operation of your system at any point, as if you had connected an instrument to it. Plots can be made of the system over time to measure responses to external stimuli. Probes can be placed anywhere in the model and the results can be graphed or viewed in table form. Model results can be copied for use by other applications.Dynamics and control analysis can be performed in the frequency domain (Bode and Nyquist plots, Eigenvalues). This helps you determine stability of the system and evaluate strategies for optimization of performance.
