*OptimizeIfOneWay (setting)

Whether settings are optimized when System Coupling detects that the data transfers are one-way.

Possible values:

  • True (default value)

    Enabled. Data model is optimized.

  • False

    Disabled. Data model is not optimized.

When this setting is enabled and the data transfers are one-way, participant solution controls are affected as follows:

  • The participants will be solved in an order determined by the data transfer flow.

  • One coupling iteration will be performed per step, so the following settings are not available:

Ensure that the participant solution settings allow for sufficient convergence within a single coupling iteration. For example, when performing a two-way co-simulation, users commonly limit CFD participants to use a small number of CFD iterations and instead rely on multiple coupling iterations to achieve sufficient CFD convergence. This strategy may not allow sufficient CFD convergence for a one-way simulation using a single coupling iteration.

The settings noted below are not relevant to a one-way workflow. If set as follows, they will be ignored:

  • AnalysisControl.GlobalStabilization.Option is set to Quasi-Newton

  • CouplingInterface.DataTransfer.Stabilization.Option is set to Quasi-Newton

  • CouplingInterface.DataTransfer.RampingOption is set to Linear

  • CouplingInterface.DataTransfer.RelaxationFactor is set to a value less than 1
