Multiple Simulations: How to see logged data in Data Inspector?

Hello,

I started with a model where I logged certain signals, and after simulation I could see the logged signals in the Data Inspector.

I then started working with the Multiple Simulations with the same model, and as I ran several design studies, I would see the resulting logged data in Data Inspector.

Microsoft Update rebooted my PC :< , and now if I run the Multiple Simulations with that same model, I no longer see the logged data in the Data Inspector. If I run the model stand-alone, without the Multiple Simulations function, I still see results in the Data Inspector.

Question: How do I re-enable display of the logged data from Multiple Simulations in Data Inspector? Or, where does the logged data go during a Multiple Simulations run?

Thanks,

Mark

Hi Mark,

To re-enable the display of logged data from Multiple Simulations in the Data Inspector, you can refer to the below steps,

1. Ensure that the preferences for the Simulation Data Inspector are properly configured. You can access the preferences by clicking on the "Preferences" option in the Data Inspector.
2. If necessary, restore all preferences in the Simulation Data Inspector to default values. This action can sometimes resolve issues related to data display.
3. Confirm that signal logging is enabled for your model during Multiple Simulations. Check the configuration settings to ensure that data is being logged correctly.
4. Open the Configuration Parameters dialog box for your model. In the Data Import/Export pane, verify that signal logging is enabled to capture the data during Multiple Simulations runs.
5. After running Multiple Simulations, review the simulation output to ensure that the data is being logged as expected. If the data is not visible in the Data Inspector, there may be an issue with the logging settings or simulation configuration.

By following these steps, you can troubleshoot and re-enable the display of logged data from Multiple Simulations in the Data Inspector.

Hello @Mark,

You can specify a limit for the number of runs to retain in the archive. The run limit applies only to runs in the archive. By default, the Data Inspector retains the last 20 runs moved to archive. To change or remove the limit go through the following steps-

1. Click on the preferences button in the Simulation Data Inspector.
2. Under the preferences dialog box navigate to 'Storage-Archive' section.
3. Select 'Automatically archive' button, this will archive prior simulation runs. and select the limit as per your requirement.

This is explained under the 'Control Number of Runs Retained in Simulation Data Inspector' in the following documentation page-

I hope this resolves the query you had!
