Hi chenkangnan,
Regarding your first question, unfortunately, I have no experience there, but hope one of the other users will comment on that soon.
Regarding your second post, if you have an issue with the CADET Code, please open an issue in the Troubleshooting section of this Forum. We are currently busy with the preparation of the CADET Workshop. I will come back to you ASAP, but if you still need help, it would be great if, in your new issue, you could share a minimal reproducible example (MRE) of your code that shows the issue that you encounter, including a comprehensive description of what you would expect for which command or method.
Kind regards,
Hannah
