The Log, Trace, and Animation tabs (which can be expanded at the bottom of the Project window) provide feedback and debugging capabilities during the execution of a simulation model. Both the application and individual blocks can post model execution state, event, and error information to the Log and Trace tabs while the model is running. The Log tab contains messages of varying severity levels about potential configuration and execution state anomalies. The Trace tab (if the Tracer is enabled) displays simulation clock timestamps and state information for individual blocks as execution progresses. You can customize the content of the Trace tab to filter out unwanted trace messages. The Animation tab enables you to select which regions of the model to animate during model execution. You can also specify the animation speed, start time, and end time for each selected region.
When parallel mode is selected for model execution, the Trace and Animation tabs are disabled. For more information about running a model in parallel mode, see the section Running a Model in Parallel Mode in Chapter 4: Simulation Models.
