Free and Porous Media Flow, Brinkman
In the Model Builder window, under Component 1 click Free and Porous Media Flow, Brinkman .
Inlet 1
1
In the Physics toolbar, click Boundaries  and choose Inlet.
2
Select Boundary 7 only (the top boundary).
3
In the Settings window for Inlet, locate the Boundary Condition section.
4
From the list, choose Fully developed flow.
5
In the Fully Developed Flow section click the Flow rate button and type V_in in the V0 text field.
Create a selection from this boundary. Selections can be used throughout the modeling process and they simplify the assignment of conditions to geometric entities. They are also beneficial for a clear overview.
6
Locate the Boundary Selection section. Click Create Selection .
7
In the Create Selection dialog, type Inlet in the Selection name text field and click OK.
This way you have created a selection for the inlet boundary as it will be used again during the model setup. The selections appear under the Component 1 > Definitions > Selections node.

In the Physics toolbar, click Boundaries  and choose Outlet.
2
Select Boundary 2 only.
3
In the Settings window for Outlet, locate the Boundary Selection section and click Create Selection .
