Hi @동빈 김
To ensure your Simulation starts from time 0 seconds instead of 4 seconds, you need to set the Simulaton start time appropiately. Follow the following steps for doing so-
- Under the 'Modelling' bar, click on the 'Model Settings' in the toolstrip.
- Under the 'Configuration Paramters' dialog box, navigate to Solver>Simulation time.
- Set the Simulation Start time to 0.0 seconds. Apply the changes and re-run the model
I hope following the above mentioned steps helps to resolve the issue and you are able to procced further!
You can additionally refer to the following documentation link for better understanding-
