I am new and tried every possible measure to run the simulation but failed. While doing the tick mark in the simulation manager, the simulation does not progress. it is stuck at 0% progress. I was using the Example file shown in the youtube video - "jEplus+EA Introduction and the example project".

The command prompt shows -

2022-09-25 00:28:44.370 [AutoCheckTask] DEBUG com.ensims.jeplusea.OptManager - Simulation request received for Copy of Project-2022-09-24_16.02.11 batch Gen-0 (15 jobs)
Exception in thread "AutoCheckTask" java.lang.NullPointerException: Cannot invoke "javax.script.ScriptEngine.eval(String)" because "engine" is null.

I do not understand what is missing in my input. Please help. Can the long name of folder cause this issue? I have tried to run E= version 8.9 which runs okay.

Maybe the Java version is wrong. It should be run in java8 environment.

If it is caused by the long name of the folder, the error would be: cannot find the path of the folder. I think your problem is more related to the @script function for pre- or post- processing of variables and results. I would suggest you go check if you have defined the script function and added the path to jEplus
