Are multiple simulation plots (using the Multiple Simulations panel) configurable, and when does the measurement take place?

Hi, I am playing around with multiple simulations (using the Multiple Simulations panel) in Simulink for the first time and have a question. I have modelled a 3-phase uncontrolled rectifier and I'm monitoring the DC voltage (nominal 540V) just as an example. In the multiple simulations I am changing the DC cable and load resistance. How do I know at what point in the simulation the DC voltage is being recorded? There are some transients in the first ~70ms of my simulation which has a stop time of 1s, so in the multiple simulations, at what time/point is the voltage measured? Can I specify at what point it records the voltage? Thanks.

Hi,

I understand you are using the “Multiple Simulations” panel to analyse a 3-phase uncontrolled rectifier model in Simulink.

The “Multiple Simulations” panel is considered for scenarios which include parameter sweeps or Monte Carlo simulations. These scenarios can be setup by configuring the “Design Study” object. The “Run All” option is used to run all the configured simulations. Finally, the obtained results can be viewed and managed in the “Simulation Manager”.

In Simulink, the time points at which a model generates output is determined by its sample time. This value can be configured using “Model Settings”.

For more information on “Multiple Simulations” panel and sample time, please refer to the following links:
