Hello Qian,

Thank you for reaching out to the Ansys Learning Forum.

This error occurs if both the top and bottom conductor sheets are shorted. Please see if 'Auto Open Region' is enabled in the solution type window. If not, an explicit radiation box should be added to the model because the default material in Ansys HFSS is PEC.

Best regards,
