Setting Simulation Process Properties

You can set simulation process information, such as the title, description, default job title, and the default log level for jobs.

  1. From the tree, right-click the simulation process.
    The Process Options dialog box appears.
  2. From the General tab, enter or edit the Title and Description.
  3. Click the Job Options tab, and enter a Job Title and Description.
  4. Optional: If you want to use a different license mode than the one specified in Me > Preferences, select a license mode for the process from the Job Options tab.

    If the license mode specified in the Job Options is different from the one in Me > Preferences, the license mode in the Job Options is used for the process. For more information about changing the licensing for a simulation process, see Configuring Execution Preferences. For more information about licensing in general, see the Simulation Licensing Guide.

  5. Click the Advanced tab, and select the following:
    OptionDescription
    Use Fixed Seed Select Use Fixed Seed to manually set the seed in the corresponding text box.

    Many design algorithms (for example, DOE techniques) use random numbers to generate parameter values (or a combination of parameter values) to use when searching the design space. If you run a simulation process with one of these design algorithms and run it a second time, you will not get the same results (though you will often get near the same solution, but through a different path). If you want the simulation process execution to follow a consistently repeatable path, you must set a fixed seed for the random number generator to use when it provides random numbers (otherwise, it often uses something like the current time in milliseconds). With a fixed seed, the random number generator always produces the same sequence of random numbers.

    Log Level Select the log level for the execution:
    Debug
    These messages are intended for debugging system or adapter code. Typically, these messages are meaningful only to program developers. The Debug log level can produce a large quantity of messages that can affect system performance. The Debug log level is the highest level and sends all six types of messages (Debug, Info, Message, Warning, Error, or SysError) to your file.
    Info
    These messages contain routine status or other informational items that are not generally significant.
    Message
    These messages contain information considered relevant to the app being run in the step, including output coming directly from the app itself.
    Warning
    These messages indicate a condition of which you should be aware but do not generally indicate a failure.
    Error
    These messages indicate an error condition caused by usage, operational data, or some other condition that can be corrected.
    SysError
    These messages indicate a software system failure. They may indicate that some part of the infrastructure has become unusable, or they may indicate a programming error. You must report these errors to system administrators for analysis. This is the lowest log level. Selecting this option sends only system error messages to your log file.
  6. Click Ok to save your changes and to close the Process Options dialog box.
