Hi Weng,
It seems that your model has internal wave ports. The error is appearinng becasue probably you do not have a PEC object defined on the internal waveports.
In HFSS, A wave port must have 'solve inside' objects on one side only. An internal wave port
would require a PEC object to be attached to and cover the opposite side before the solution can
proceed.
I would suggest you to refer HFSS help PDF and look for "Automatic PEC Creation on Wave Ports"
This section discusses more about internal waveport and how to create a automated PEC backing object.
Thanks,
