• Select Geometry on the left-hand side of the coupling configuration window.

• Set the pipe diameter to 0.08m.

• Select Coupling Scheme on the left-hand side of the coupling configuration window.
• Set the coupling boundary control parameters as follows:

– Pressure equation tolerance: 0.01
– Outflow velocity tolerance: 0.01

– Mass flux tolerance: 0.01
Assigning Boundary Conditions: To assign the water inflow boundary condition the Z min surface

• Select Z Min from the drop-down list at the top of the BCs tab

• Highlight ZMin0 in the surface tree

• Check the light grey square at the line corresponding to the water inflow boundary condition

• Click

ZMin 0 in the surface tree is colored with the color associated to the water inflow boundary
condition after being assigned.

• Proceed as above to assign the corresponding boundary conditions to the remaining surfaces
using the information given below
