All settings for the Scenario Manager are stored in a folder named Scenario Manager with the same folder as the 20-sim model. Suppose you have stored a 20-sim model as:
C:\temp\models\my 20sim model.emx
Then the Scenario Manager files are stored in the folder:
C:\temp\models\ScenarioManager\my20simmodel\
Inside this folder you will find a log file
C:\temp\models\ScenarioManager\my20simmodel\build_server_log.txt
Inside the log file you can see the outcomes of the Scenarios that have been run.
If you want to copy the Scenario Manager with a 20-sim model, make sure that you copy the folder
ScenarioManager\my20simmodel\
with the 20-sim model.
