Hello Yushu Zhao,

Thanks for posting your query on Ansys Learning Forum. I could see that mentioned setup steps and expression are correct to compute the quality factor of the structure.

However, I suspect issue with some settings especially Port creation. This will have to check with the actual model. If you have access to Ansys Techical support, please raise a service ticket and support engineer will connect you to resolve the issue.

Thanks.
