We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

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,

Anchal
