i am designing a dual band power divider at 1.8 GHz and 2.6 GHz. When i analyze the design i get an error stating port refinement error ort 1 is assigned to an internal face.
I am attaching the hfss file along with it.Please tell me what to do with this?

To solve it:
Lump port use for internal port:
-you can change the port to lumped port if you need to make internal port like your model. you can see a link below

or
-Wave port use for external port;
you need to revise the air model by make the air box over the substrate and make the wave port at external side.

some link may help you: https://www.edaboard.com/threads/116727/

for my suggestion
1. you should revise the air model, make the air model above substrate and apply the wave port.
2. reduce the the model size (cut the left side and right side) to get the small model that help you to reduce time for simulation
3. the resistor value , you should select the standard value.
4. please carefully design the phase of each port that should be same phase.
