Optimization with wrong subscripts error

[aliakhavan89]

When there are issues with the subscripts defined in the Vensim Optimization Control (.voc) file, Vensim reports 'ERROR: Problems encountered in the simulation.' when running the optimizer. It would be helpful if more targeted information is provided when this error is shown.

Thank you very much.

Do you have an example you can provide? I can probably make changes very quickly.

[aliakhavan89]

Does this work?

I'll see if I can improve the error reporting. Maybe if I just change

ERROR: Cannot find constant in model

To one of the following depending on what is in the optimization control file.

ERROR: Constant not found in model, cannot continue.
or
ERROR: Constant found in model, but no subscripts in optimization control defined. Are subscripts missing?
or
ERROR: Constant found in model, subscripts appear to be incorrect. Are subscripts correctly defined?

Thanks a lot! It can also happen when subscripts are defined incorrectly.
