Hi i have duct inside the tunnel and the duct is set as interface, what geometry i have to use as a duct?. I've set the duct as slice material is that correct ? and also how do i handle "mesh file exporter could not resolve cyclic dependencies"

I didn't understand your question. Could you please provide more clarification, possibly with illustrations? Additionally, what is the objective of the simulation? and which tool are you using?

If I'm understanding correctly, your goal is to facilitate the flow of fluid through the tunnel and then into the pipes, is that correct?
If so, here are the steps you can follow:
1: Ensure that you prepare the CAD appropriately in Ansys Discovery or Spaceclaim. This involves subtracting the pipe geometry from the tunnel geometry so that they become two separate bodies and do not overlap. Afterward, you can share the topology between the tunnel and the pipes. There will be 3 fluid cell zones in this case (1 tunner and 2 pipes)
2: If you are using Fluent Meshing Watertight workflow to create the mesh, it's important to convert all fluid-fluid boundary types from 'wall' to 'internal' when describing the geometry. This ensures that the fluid can flow seamlessly through different fluid cell zones.

Alternatively, you can extract the fluid domain throughout the entire solid geometry, which should also work. By doing this, you will end up with a single fluid cell zone.
