 # DirectSImulationSettings – Setting a direct simulation

 Last update: 17.07.2025 

The following script sample shows you an example on how to set a Direct Simulation.

**GetDirectSimulationSettings** returns a **DirectSimulationSettings** object that allows you to modify simulation settings.

The **DirectSimulationSettings** object includes four main methods:

- SetPropagationErrorAnalysis(*bool propagationErrorAnalysis*)
- SetDispersion(*bool dispersion*)
- SetFastTransmissionGathering(*bool fastTransmissionGathering*)
- SetAutomaticSaveFrequency(*int directTemporarySave*)

**SetDirectSimulationSettings** applies the changes made with the **GetDirectSimulationSettings** function.

```ironpython
directSetting = simuDir.GetDirectSimulationSettings()
directSetting.SetPropagationErrorAnalysis(False)
directSetting.SetDispersion(True)
directSetting.SetFastTransmissionGathering(False)
directSetting.SetAutomaticSaveFrequency(1800)
simuDir.SetDirectSimulationSettings(directSetting)

```
