UpdateControl (singleton)

Available for AEDT participants running an Eddy Current solution when the coupled analysis is steady.

Controls the frequency with which the participant performs updates during the execution of a coupled analysis.

Tip:  These settings are particularly useful for mixed steady-transient analyses. Specifically, moderating updates of the steady participant can significantly reduce execution time, with a modest effect on transient accuracy. For more information, see Transient Analysis Type in the System Coupling User's Guide.

Note:

  • Every participant performs an update during the first iteration of each run (that is, during the first step of both initial and restarted coupling runs), regardless of its UpdateControl settings.

  • When beta features are activated, update controls are available for all other coupling participants. For more information, see Participant Update Control Settings in the System Coupling Beta Features documentation.

Tip:  Shown in the GUI as the Update Control branch.

UpdateControl contents:

 

*Option (setting)

Specifies how often the participant will perform updates.

Possible values:

  • ProgramControlled (default value)

    Participant updates are always enabled. The participant performs an update during every coupling iteration.

    This option is active by default. To change this behavior, you must explicitly set Option to another value.

  • Every Iteration

    Participant updates are always enabled. The participant performs an update during every coupling iteration.

    This option behaves the same as the ProgramControlled option but is explicitly set.

  • StepInterval

    Available for AEDT participants running an Eddy Current solution where the coupled analysis is steady.

    The participant performs an update during coupling steps at the interval specified by the UpdateFrequency setting.

  • Suspended

    Available for AEDT participants running an Eddy Current solution where the coupled analysis is steady.

    Participant updates are suspended until you set another value.

During coupling steps in which updates for a participant are suppressed (via either the StepInterval or the Suspended option), the participant also does not engage in data transfers, either as a sender or receiver. Non-suppressed participants continue to work from the data obtained from the suppressed participant's last update.

Note:  If under-relaxation is applied to data transfers for which an AEDT participant is the source, the target values may still be updated during suppressed steps.

Tip:  Support for the StepInterval, Suspended, and UpdateFrequency options for all participants is available as beta functionality. For more information, see Participant Update Control Settings in the System Coupling Beta Features documentation.

Tip:  Shown in the GUI as the Update Control | Option setting.

 

*UpdateFrequency (setting)

Available when the UpdateControl.Option is set to StepInterval.

Interval at which the participant executes its updates.

For example, with a value of 5, the participant performs an update during every fifth coupling step: 5, 10, 15, etc. (This is in addition to the standard update for the first coupling step of every run.)

Accepts integer values greater than or equal to 1. Default value is 1.

Tip:  Additional participant support for the StepInterval, Suspended, and UpdateFrequency options is available as beta functionality. For more information, see Participant Update Control Settings in the System Coupling Beta Features documentation.

Tip:  Shown in the GUI as the Update Control | Update Frequency setting.
