'NoneType' object has no attribute 'model_file' error

I am working with a Stella itmx file, and getting a ‘NoneType’ object has no attribute ‘model file’ error. The model runs, and the initial values replicate those in the Stella model. The final values are fairly close to the values I get when I run it in Stella, but they vary somewhat.

Hi Bruce,
