About System Experiment

A system experiment is a PLM reference which links a logical or functional model with its simulation data.

This section deals with information you should know before working with system experiments.

The following topics are discussed:

System Experiment

The system experiment consists of three components:


  • Model: The model to be simulated and its associated representation.
  • Scenario: The parameters that define the simulation, including scenarios, excitations, and probes.
  • Result: The postprocessing data, including watch lists and plots.

The model is edited within the VPM Functional and Logical Editor workbench.

The simulation specifications and results are edited within the System Experiment workbench.

When creating a system experiment, an empty scenario is automatically created.

Model

Different models can be simulated in the System Experiment workbench:


  • Functional models with state logic behavior.

    Such models are created from the Functional and Logical Editor workbench.

  • Logical models with state logic and/or dynamic behavior.

    Such models are created from the Functional and Logical Editor workbench.

  • Stand-alone dynamic behavior models.

    Such models are created from the Dynamic Behavior Modeling workbench.

Scenario

This section gives you a definition of a scenario.

Definition

A scenario aggregates all the specifications for a simulation.

Those specifications include:

You can create as many scenarios as needed, by Adding/Editing a Scenario.

Plot and Watch List Probes

The probes contain the stimuli and the observations to be applied to the system.

During a simulation, the probes collect the results. Variables are then displayed in a chart (plot) or in a separate list (watch list).

A plot can display several curves (one curve for a scalar variable). Several plots can be specified for a single simulation, so several windows can be displayed during a simulation.

Results

This section provides you with information about results.

When a simulation is computed, the variable values are displayed in:

  • Watch lists (in the Signals Monitoring window)
  • Plot window
  • Simulation Diagnostic window

You can visualize and manage these results in the Variable Browser.

See Working with the Variable Browser.

These results are also stored into the system experiment representation.

See Viewing Computation Incidents.

Export

You can export in external files:

PLM Express

The System Experiment workbench is available with a PLM Express installation.

Furthermore, such installation allows you to use specific search keywords.
