I want to incorporate 1-D fluid flow advection links in my domain. I do not want to solve for flow. How is this possible?

You can use Network objects for this. Network objects create thermal network which can be used in this scenario. Use the following steps

1. Turn the Cabinet to `None`. There will be no fluid regions in the model and no flow will be solved.

2. Identify the geometry along which 1-D fluid flow is going to take place. Also identify the inlet, outlet and the mass flow rate.

3. Create network object to simulate the 1-D fluid flow advection links. Create a network objects with inlet and exit boundary nodes, internal nodes and face nodes.
a. Create two boundary nodes. Specify the inlet heat or temperature to one and make the other as outlet node.
b. Create internal nodes. Connect them together in a 1-D pattern with inlet and exit boundary nodes at the two ends. These nodes can have power, mass and heat capacity.
c. Use Capacitance links between boundary and internal nodes to define the mass flow rate.
d. Create face nodes in the network object. The number of face nodes should be equal to the number of faces in the model exposed to this 1-D fluid flow. Move the geometry of this faces created in the network object to the right geometrical location.
e. Now connect all the faces that get exposed to this 1-D fluid advection stream to the internal nodes with Resistance Links between the face and the internal nodes.

4. The accuracy of the thermal results in these scenarios depend on the heat transfer coefficients applied and the accuracy by which 1-D advection link relates to real flow.
