Thanks for updating your post.
Before looking deeper into the code it would be interesting to know how you selected the model and how you determined the values of the model parameters.
Also, I’m still curious as to why you are using CADET-Python directly instead of CADET-Process.
Since this is a very broad topic, I would also recommend visiting our next Office Hours where we can give you some hands-on support. Unfortunately, you just missed the last date yesterday. Next one will be May 8th.
