Configuring Execution Options

You can specify the Dymola executable file, set options that can be used when this executable file is launched, and set specific start and end times for the component execution.

  1. From the Dymola Component Editor, click the Execute tab.
  2. In the Command Line area, specify the location of the Dymola executable file (dymosim.exe) command line options when launching the Dymola executable file:
    1. Click Find dymosim.exe, and navigate to the Dymola executable file in your directory structure.
    2. Click Open.

      The file name for the Dymola executable appears in the Command Line text box. By default, the name is followed by -s <input file name> <output file name> as shown in the example below.



  3. Type the remainder of the command line following the program name.

    For more information on additional Dymola arguments, see the Dymola documentation. For more information on standard Isight arguments, see About the Command Line Syntax.

  4. Click Verify Commands to check the syntax of the command line.

    If there is a syntax error, the Dymola Component Editor displays an error message describing the problem.

    If the command is valid, a Command Line dialog box appears showing how Isight will interpret the command line—the command name, where arguments are split, and any I/O redirection. The values of the substituted parameters appear, instead of their name.

  5. In the Parameter list, select a parameter to use as an argument.

    • To add an existing parameter, select it from the parameter list and click the button.

      Isight adds the parameter name to the Command Line text box at the current cursor position and highlights it in green, indicating that the value will be substituted at run time.

    • To add a new parameter, click the button and configure the name and other details in the Add Parameter dialog box, and click the button. The new parameter will have data type Real, but you can change the type on the Design Gateway Parameters tab.

    To delete a parameter from the arguments list, click the parameter and press the Backspace key.

    For more information about working with parameters, see About Entering Parameters.

  6. Set the Execution Timeout in the corresponding text box. This setting represents (in wallclock seconds) how long the component is allowed to execute. After this time the component will be interrupted and then either retried or the simulation process flow will fail.
  7. Click Log Standard Output to send any messages that Dymola writes to standard output to the Logs tab on the Runtime Gateway.
  8. Specify the following options in the Advanced Options area, as necessary:
    OptionDescription
    StartTime Set the time (in wallclock seconds) for integration to start. The default value is 0.
    EndTime Set the time (in wallclock seconds) for integration to end. The default value is 30.
    Increment Set the communication step size. This option is disabled if the value in the Increment text box is 0. The default value is 0.
    Interval Set the number of communication intervals. The default value is 500.
