Chapter 7. The Qtenv Graphical Runtime Environment

Features

Qtenv is a graphical runtime interface for simulations. Qtenv supports interactive simulation execution, animation, inspection, tracing and debugging. In addition to model development and verification, Qtenv is also useful for presentation and educational purposes, since it allows the user to get a detailed picture of the state and history of the simulation at any point of its execution.

When used together with a C⁠+⁠+ source-level debugger, Qtenv can significantly speed up model development.

Its most important features are:

network visualization
message flow animation
various run modes: event-by-event, normal, fast, express
run until (a scheduled event, any event in a module, or given simulation time)
simulation can be restarted
a different configuration/run or network can be set up
log of message flow
display of textual module logs
inspectors for viewing contents of objects and variables in the model
eventlog recording for later analysis
capturing a video of the main window
snapshots (detailed report about the model: objects, variables, etc.)
