Run the Experiment and View Results

To apply all network settings and compute network-level statistics on your STK scenario:

  1. Set your experiment runtime preferences by going to the STK Edit Menu->Preferences...->QualNet Interface page. You can also elect to save the STK scenario to the QualNet Experiment folder at runtime.

    2. To save the QualNet experiment files without running the experiment, click the down arrow on and select Export Experiment.

  2. Click . The simulation is started and the Run Control widow is displayed. The Simulation time and Progress bar enable you to monitor the progress of the run. You can interact with the run in any of the following ways:
    • Pause and then continue the simulation run.
    • Stop the simulation run.
    • Restart a simulation run that was stopped.

    The QualNet animation is dependant on your Animation and Event Type selections (Packet Received animation, Unicast animation, and Dropped Packet animation) from the QualNet Interface Settings preferences page.

    The following QualNet Experiment files are saved to the folder specified on the QualNet Interface preferences page:

    • Scenario configuration file (*.config), which is the primary input file for the QualNet application and specifies the network scenario and parameters for the simulation.
    • Qimap file (*.qimap), which contains the mapping between STK objects and the QualNet nodes and is required by both STK and the QualNet application.
    • Application configuration file (*.app), which specifies the applications running on the nodes in the scenario and is referenced by the scenario configuration file.
  3. When the simulation is completed, the Statistics file (*.stat) is loaded into the Stat File viewer. The Statistics file is the primary output file generated by a QualNet simulation run. The Statistics file shows desired statistics, including Throughput, Broadcasts Sent & Received, Packets Queued, Packets dropped, Route Timeouts, and Packet Times. Graphs are shown by node ID(interface ID). For example, 2(0).

    4. If the Stat File viewer is not automatically displayed, you can enable it on the QualNet Interface Settings preferences page.

  4. Click on any parameter in the Stat File viewer to display its statistics from the simulation run.
  5. To display the output log, click . The output log displays the status of the simulation run and any runtime errors.

Display Results from a Previous QualNet Interface Run

To display a file generated from a previous run of the QualNet Interface, click and select the desired stat file.
