I have terminal port error in Hfss simulation

help me about this error
Port refinement, process hf3d error: Terminal Source1_T1 on port p1 contains a non-conducting edge. The terminal may need to be assigned manually

Both edges of the port must be conductor (or PEC). The error says that one edge is not a conductor.

Thank you amihomo
how can assigned manually terminal port?

also this error in Example ? 180° Ring Hybrid user guide hfss^10 , I apply all the steps in the example, but before work analysis give me this error
Port refinement, process hf3d error: Port p1 is assigned to an internal face Only allowed with lumped ports
Please note that I when disconnect the port for Trace give me another error when plugged This error appears

maybe your configuration is wrong, you should check HFSS tools > option> HFSS option >general >auto assin terminal port .my english is poor,i hope you can understand my words and also this can help you!
