Description

Use theState Explorerto view individual state dynamics of your model

Open the States Explorer

  • Profile the model using theSolver Profiler. Ensure that theContinuous Statesparameter is enabled.

  • SelectStatesin theExploresection of theSolver Profilertoolstrip.

This example shows how to use States Explorer to explore Newton Exceptions.

To begin, open theex_spi_show_zcmodel, clickDebug, open the drop down menu ofPerformance Advisor, select Solver Profiler.

Enable theContinuous Statesparameter in theConfiguresection of the toolstrip and run Solver Profiler.

When profiling has completed, launch State Explorer. SelectNewton/DAE Exceptionin theFiltersection of the State Explorer toolstrip.

There is an increase in the density of Newton exceptions through the simulation. Zoom in on the State plot between the 5 and 6 second mark.

Around 5.48 seconds, the bouncing ball being simulated in the model comes to ‘rest’, hence the isolated single Newton iteration exception.
