Simulate a SysML Model

You simulate a SysML model from a Parametric diagram, using the 'Simulation Configuration' dialog.

The Parameters panel lists all of the parameters that can be assigned input.

Select each of the required parameters and click on the right Arrow button to assign them as input.

Parameters designated as input parameters are listed in the Inputs panel on the right.

There must be at least one input parameter assigned for the simulation to execute.


Assign a set of values for each of the designated input parameters.

For each input parameter, in the 'Input Values' panel select one of the two possible value kinds:

  • Discrete - To enter a constant or a comma-separated range of discrete values
  • Range - To enter a range of values beginning at the 'From' value and ending at the 'To' value; the input values are incremented by the 'Step' value


Specify the classes of output value:

  • 'Parameters' - To output the parameters' data, select the checkbox
  • 'Variables' - To output the data generated within each internal variable, select the checkbox; internal variables are automatically generated by the simulator


Specify how the simulation results are to be reported.

The 'Output Format' panel enables you to choose how the simulation outputs the simulation data:

  • Plot To Graph: To plot the results on a 2-dimensional graph, select the checkbox; if you select this option, you must specify an input parameter for the plot's X Axis
  • Title - To enter a title for the graph, type in the title text
  • Output to File - To output the results to a CSV text file, select the checkbox and type or browse (click on ) for the file name


Click on the OK button to execute the simulation.
